Reminds me of tramadol. To get a real high from it you needed to take whatever your usual dose was all at once, then redose 50mg every few hours to get the most from it, otherwise any high you got would be very limited. This then of course increases the seizure risk because you keep redosing, but it's the only way the bloody stuff actually works. Same is true for the medical effects which is why the NHS script like 3-4 doses a day when they hand it out.
Of course these days tramadol doesn't get me high anyway no matter how I take it. Very curious how the way my body metabolises tramadol has changed so much over time.
It's interesting that nowadays I get nice eupohoric buzz from even from 60mg codeine while opioid naive I didn't feel anything. Same goes with loperamide, 32mg loperamide didnt feel anything evne with zero opioid tolerance, but now it gives me nice mood boost when not having tolerance, 64mg gives euphoria already. I get good high from 20mg oxycodone, but back then not much. So my tolerance have gone even bast the zero from the times of opioid naive times (15 years ago). I don't use daily anymore, but my body metabolizes them different, also methadone and buprenorphine gives now strong dysphoria in any normal "recreational doses" but back then very strong euphoria, now I just need to take maybe 0,3mg bure to get good mood or 5-10mg methadone. Not that I find them very nice feeling anyway,I prefer codeine, tramadol and loperamide over oxycodone, methadone, buprenorpine or pure morphine, but opium is still best, but it makes me somehow depressed still euhporic but depressed same time, strange thing. Benzo effect have changed over year and I usually return to baseline toelrance, I don't get very easy benzo wd's, it takes at least 2 months 2mg xanax 2mg klonopin daily use before I get 1 week insomnia, but pregabalin gives strong WD's just from 5 days use. I've never devloped much tolerance for speed and it always use as 15 yearas back because I use it 6 times a year. Also for some reason quetiapine gives me very good mod next but only for 1 week use, if its over 10 days I get that zombie feeling. Should start own thread for unusual drug effects.
Tramadol still gets me very high, I've never IV'd anything so that might help, even that I have used 200mg oxycodone for logn periods of time and opium and fentanyl, still I get codeine high, just from 60mg, 30mg gives jsut little mood boost.
