My bowel problems went away months ago, they were only ever mild with me anyway, the worst affects aren't on the gut with celiac & it heals within a few days of going gluten free, that's why it's so hard to diagnose, it took years until I realised it was a diet problem. I wouldn't recommend bk-2c-b for gut problems either, or anything else really except a fun, long lasting, relatively clean feeling, mild controllable trip. It's just helped to treat some of the specific complications I had & aided my recovery a little. My stomach is strong now, but I've been lacking vitamins due to celiac over a long period, malabsorption, because my gut has been fighting the gluten, this has caused a lot of other physical problems, like chronic joint pain, particularly in my back, depression, underweight, weak, lack of energy, etc. They've all been recovering since I went on the diet, just a bit too slowly for my liking. I had years off taking any drugs like this because of my health problems, was just codeine & weed for the pain, now I'm on the mend, just some residual joint pain & stiffness in my back was the main thing annoying me & the tail end of the depression. It's much improved after the last two weeks, snapped straight out of the depression after the first dose, just been cracking my back for two weeks, moving vertebrae that have been locked together for years & my back seems to have been recovering at a much faster rate for the last two weeks, far from a magic cure, but noticeably better. Stretching feels good too, maybe it's a yoga drug?
It gives a nice body effect at low to medium doses, it increases flexibility & takes away pain, it seems to be quite a potent anti-inflammatory. Higher doses cause more circulation & stomach problems, but on a normal dose it seems an easily manageable body load, very pleasant overall.
The nauseous feeling only comes if I've got a full stomach & at higher doses. Stick to light meals & snacks, light doses. It also seems to have subsided over the last two weeks, I only noticed at first (probably dose dependent, but maybe some tolerance to the nausea develops). It's no worse than MDMA for nausea imo, similar rules apply - don't eat too much & take a dump, then I'm fine. I've noticed food tastes fantastic too, got the munchies on it a bit, but got to keep the food light, if i eat too much I start to feel nauseous. That's another reason I'm stopping, I need some big meals to get back the weight I lost. It's not too terrible weight loss, but I was underweight before.
I can't speak for everyone on the tolerance or side effects, but I've had no serious ones, so far, I am probably a special case, so don't trip for two weeks, kids. It could be enough to send some people crazy, but it's nothing like tripping on acid or mushrooms for two weeks, at least not for me, I'd never consider acid or mushrooms for two weeks unless it was microdoses, barely threshold doses at most & it seems easier on my mind than microdosing mushrooms. I didn't get any tolerance from doing just threshold doses of mushrooms daily for weeks in the past either. I've been doing much more than threshold doses of this most nights. It's nothing like higher dose lsd tolerances, or even mdma. Despite it being a two week binge I've been able to control my doses reasonably responsibly, i never did over 300mg at once & was never tempted, but I have tripped hard for several days in a row & haven't needed to use any more to reach similar effects as the previous night.
I did expect there to be some tolerance, but I haven't encountered any yet, possibly even some slight reverse tolerance. I've been dosing more for the body effects than the mind trip though, not going for intense trips since the first week, not had over 150mg any day this week & mostly under 100mg. Higher doses might develop a tolerance faster, not that you'd ever want to try doing that for two weeks.
It's not no observable side effects, but they've been relatively mild, considering how hard I've been tripping & for how long, I've been able to cope with them easily, so far, ymmv. I've had some weight loss, very short mild headache & a little jaw tension on a comedown after a heavy dose or a few days constant tripping (no headache or anything from lighter trips), vasoconstriction, a little confusion, slight nauseous feeling if I eat too much while I'm tripping, body feels floppy & uncoordinated (that should wear off when I come down). Less subjective side effects than taking low dose mdma or mushrooms for two weeks when I was younger, so far. Long rambling posts on forums are another side effect too. All the expected side effects, pretty much, but much lighter than if I'd done some other powerful recreational psychedelic or stimulant, except the vasoconstriction feels just as bad, not LSA seed levels, but maybe worse than MDMA, as bad as speed for that probably, but without such a high heart rate. I have a feeling if I went for much longer on it I'd develop more problems, possibly start feeling slightly uncomfortable, maybe another few days & my legs would feel like somebody just spiked me with 5 hbw seeds. I have lowered the doses for the last week to moderate the side effects. I'm just well used to having worse immediate side effects than this from drugs, especially from a 2 week recreational psychedelic binge.
A light snack, piece of fruit or something, caffeine & vitamin pill seems to totally cure the slight comedown, for me, if there is one.
It does feel very 'refined'. I wouldn't say lacking character, just maybe a little shy, reserved. I mean I'm tripping so hard just off 70mg that I can almost understand market research questions like "If this brand was a person, what character traits would it have?", I'd never previously considered assigning characters to drugs or brands or any inanimate objects until I'd taken some of this. I know some other people do that naturally, now I can feel empathy for them. Feel like I'm understanding languages that assign genders to random objects better now. Haven't really studied Spanish at all since I was at school, but now it feels like I can understand it as well or better than then. I've seen sounds as colours, had full on synaesthesia at the peak of some experiences on it in the first week, yet I can still remember it all & still felt I had some level of control, almost like sat sober watching a psychedelic effect I could turn on or off, close to some meditative states. Some real top end psychedelic experiences are possible on this on higher doses, even lower doses can be pretty impressive, or I can just sit feeling fairly sober but a bit wobbly, or any state in between those extremes & I can switch between those states fairly quickly at will, almost as if it's instant no-effort meditation, it's very malleable.
My daily noopept use might have helped me feel more in control too, it possibly lessened some effects & potentiated others too, maybe it affected the lack of tolerance forming, it seems to make most drugs 'clearer' feeling, heard of people combining it with lsd to remember their trips better. I've been taking gingko too & multivitamins. I'm a daily cannabis smoker too, usually, but I've been smoking less, had a few days without too, feel like I could quit it more easily now, at least if my back doesn't get worse again & if I actually wanted to stop, I'll probably just cut down. I've stopped smoking cigarettes too, gone straight from 10 a day to an e-cig, I'm a bit compulsive on the e-cig when I'm tripping, but I feel like bk-2c-b made it easier to stop real cigarettes than just the e-cig. It's not going to do much for real hard addictions, maybe help quit a few small bad habits, but I can see how more powerful psychedelics could possibly treat addiction.
My intention was just to try to have a fun little one off trip to get me out of a slight lingering depression leftover from the celiac disease, but when I noticed the body effects, lack of tolerance too & how easy it seems for me to control the experience, I realised it could do more for me. My brain feels a little overloaded after two weeks of it, but I've been worse from a single night mushroom trip before.
I'll update if I notice any problems with withdrawal, I don't expect any.
