Ive been using tianeptine 3-4 times a day (sometimes 5) at approx 40-80mgs depending. If opiates are your problem, I would recommend it, just because the cravings go waaay the fuck down with daily dosings of it- for that matter most cravings period. Sure the shit has its own WDs over long period use but at least its legal, easy to get, fairly cheap (compared to other addictions anyway) and you can function on it just fine at work and such, even when taking a larger dose than normal.
Also, it seems to have an effect on my sex drive in a positive way.
