Experianced with meph for 12 months. Both the 800mg 12 hr binges, and light more modest 300's. The mixing with booze, M1. Dimetho. The bombing the railing.
10 years ago, a few beans, some woodrose, mushies, lines, several tabs etc
8 weeks ago tried pv. 1mg, followed by 5mg over 2 hours. Week later, did 3mg bumps and totalled 15mg in 5 hours. Week later 25mg in 3mg bumps. So far so good, notice the tolerance building quite quickly.
PV + Meph is actually a nice combo, for about 8 hours (35pv + 300meph in small bumps of around 3mg pv and 30meph from 9pm to 5am ). Then the inevitable meph comedown occurs. Not usually a big problem....except now there is large CNS stimulation that is showing NO sign of slowing, turning the normally mild(ish) comedown into a crash. Spend next 8 hours REALLY concentrating on trying to keep calm, the slightest and I do mean slightest milisecond of fear/doubt/anxiety allowed to be accepted as truth and heart feels like it will explode. Cannot watch TV, read, walk, talk or do anything that asks the CNS to compute anything such as sound, colour etc is WAY too much. Just stare at blank space on wall and focus on trying to be a bit calm.
The slightest noise or glance over at anything more noxious than a house plant overwhelms the senses and sends the heart and body racing even further. Again, controlled in a millisecond to defcon2 (very fast and loaded) because a realisation that this is the worst position ever been in and as close to making an exit from life as 15 years of drinking, naughtiness and motorbike crashes has provided.
Need water (have been on 0.5lt an hour min as normal), HAVE to bump meph to just be able to get to the kitchen and hear the sound of running water without completely freaking out.
In the end I HAD to keep doing little bumps of meph to be able to get periods of relative calm and walk to get water. And when I mean relative calm, its still worse than anything I've ever experienced (ie still defcon 2 and not 1). When the meph wore off, quicker and quicker, this of course left even MORE stimulation but with added terror. I totalled another 100mg over the 7 hour freakout.
I cannot put into words the abject horror this nightmare was. How much focused brain power was required just to tell my body to be cool and calm (ie remain at 180bpm, not 220) and not explode with heart failure. The mind was calm(ish), I mean I could think, albeit at 900mph. But the body was really under MASSIVE load. The likes of which I've not seen and never thought possible for the body to withstand.
I dared not risk taking any downers. The only things I had were kratom and booze. Kratom is great stuff, I really like it. But its a fine line between a sedative and mild stimulant. There was no way I could risk another stim, and I recognised there was no way to prepare it either. I was in no state.
At around 6pm I was finally not having to spend ALL my energy and brain focus on not controlling my body load. Went to sleep at 10pm (25 hour after 1st dose). Slept badly with massive pain through large amounts of stomach acid and trapped air. Trying to differentiate between chest pains and heartburn.
Could not eat / speak for next 2 days. Picking at rice and trying to swallow milk based protein (which IS always a briliant way to bounce back).
Took 1 week before I stopped jumping at every noise outside, took 2 weeks before being able to walk 1/8mile and not be completely out of breath. I mean totally knackered / exhausted.
Kept thinking about a task and then doing something totally different. ie Pick up a cup to put in the cupboard and instead opening the cutlery drawer.
I'd clearly fried some brain cells and it was busy having to rewire.
Going from being a member of a gym, lifting weights, treadmill, cycling etc to not being able to walk and breath properly for 2 weeks. I started to wonder if this was permanent, if this time the luck had run out and indeed that fine line had been crossed. Bearing in mind that I know the power of a negative/positive attitude and anxiety and to recognise these things are not permanent....usually...
But even with that, its been a major struggle and scare.
Took 4 weeks to stop automatically thinking about things in a negative way. In the past the occasional blues had been recognised as such and laughed off on the road to recovery. But this was completely different, unlike anything thats happened in the past.
You read about some peoples descriptions of bad experiences, but without a yard stick, the words have little meaning. I know people will read this and have no clue as to how bad it was. Even I can't really begin to remember to describe. When I come close to putting my mind back enough to think to describe, I feel very agitated, physically sick almost.
I wanted to post about it. But its taken 5 weeks to be able to think about it without feeling really sick.
I think this is very similar, if not in fact, the same reaction to extreme shock. Such as those described by people who have had some sort of trauma.
I thought I was experienced enough to know limits. I ate well, slept well, planned ahead with my usual routine of making sure everything is where it should be and that some cover is available in case.
But I never expected to get it soooooo badly wrong. I totally messed up and am EXTREMELY grateful that the years of eating well and training right may have saved me from exiting the party early. I was also EXTREMELY lucky, I know that.
Needless to say I've gone totally back to basics. Eating balanced food, walking often, training lightly and focusing on positive action. But I also recognise that I will never be the same. It's clear my body has taken a hit and its clear that my brain is running a good 20% down on its previous performance.
You play with fire. You act stupid, you run the risk. But seriously, I'm usually very careful and have never got it so wrong before. Also, while the pv was higher, the relative amounts of meph was still well under 500mg. These are not enormous numbers, particulary when you hear about kids doing 3grams in 2 days etc
I'm not sure if this post is of use. Sometimes something like this can cause anxiety where it needn't be. But all I can say is that my worst experience on anything measured 30mph until that day where it now sits at 500mph.
Needless to say, I'm going straight for a long while. I've not had any booze, tea, coffee, anything in 5 weeks. And to be honest, its REALLY crap

Seriously, I'd much rather be able to enjoy a little in moderation right now as I had been, and really wish that day had never happened.
But just grateful I got another chance.
Well, that was a long post just to say that possibly meph+pv is not a good mix.
So, same again this weekend
EDIT:
Also, another minor observation. Meph makes it impossible to ejaculate, this makes sex a lot of fun, but also sometimes irritating after 8 hours and 3 loo breaks. PV has the opposite effect. The second time ever, and I lasted a ridiculous 3 minutes once we'd decided to crack on. It was like being 13 again....but with less self control.
This has nothing to do with the above story, just to say that previous encounters had been a lot of fun to say the least.
