Tried Tapentadol for the first time last night so thought I'd add my feelings on it!
Some background, I have opiate experience with: codeine, dihydrocodeine, tramadol, O desmethyltramadol, AH7921, Heroin, morphine (once in hospital), oxycodone (didn't do much as didnt have enough)
I am a regular codeine/DHC user as in once or twice a week and have a tolerance (require around 900-1000mg of assorted codeine and DHC to get to a good place)
Tapentadol was mentioned to me the other day so thought I'd give it a whirl given how expensive codeine is becoming to maintain. Got a strip of 10x 100mg tablets.
Dropped 150mg on an empty stomach and a couple of beers. Felt a small buzz developing after about 30-40 mins. I would try to compare it to Tramadol but it has been over a decade since I've taken tramadol and honestly it wasn't memorable enough for me to say. Standard low dose opiate warmth, felt a little light
Dropped another 50mg with another beer about an hour in and the mild buzz became mild/moderate. Still nothing major. Was kindof regretting not going with codeine for the evening so dropped 200mg of codeine
Over the next hour the buzz developed into something quite pleasant and over the next few hours I dropped another 100mg in 50mg increments. I did not get any of the delirious effects or any particularly stimulated NRI effects. Just a nice even euphoria and general good feeling. It did however come in waves sometimes with some flatter periods. I never quite achieved the warm euphoric glow I generally get from codeine but it still felt good.
I slept easily and very deeply after (weirdly i had a dream that I was delirious and talking to myself at a pharmacy counter but I think this is because I'd read so many reports of people becoming weird on this substance)
Either way it was generally positive but nothing mindblowing. One note I will make is that I was not planning at all to take over 200mg of this but it is quite compulsive. Those "flatter" phases combined with the "never quite overwhelming" low level euphoria triggered a desire to get more fucked up which I imagine could be dangerous
Cheers
