The anecdotal reports of Tianeptine led me to believe that it's an antidepressant with cumulative effects. So I've been taking 2 little capsules of Tianeptine a day and it's a pretty subtle effect but I think I like it, although I didn't experience any pronounced cumulative effects.
It adds a background hum of happiness. The best way I can describe it, if you've ever done good ecstasy or MDMA and you just had this feeling of inner happiness and satisfaction. It's like that, although not to such an intense degree minus the really pro-social effects of MDMA. I didn't find myself being impetuously affectionate with everyone. The effect half life seems a little short, I notice a subtle optimism for about 3-4 hours after dosing.
