so surely if I've only been taking it since Monday it probably wouldn't have done much anyway would it so there shouldn't be anything like that I would assume?
I read somewhere on a forum that someone felt more euphoric while taking sertraline while on cocaine but other said the opposite, I'm guessing its different for everyone like everything else.
I'd be careful with the alcohol mostly. Alcohol and SSRIs don't tend to mix well. I don't see a problem with the cocaine but I'd highly advise against all drugs on SSRIs because it can mess with the reasons it was prescribed in the first place with the upper comedown and all messing with your brain chemicals.
Probably best avoided as others have suggested but if you insist on doing it anyways best to go slow and use as little as possible.
I also wanted to correct you. Cocaine most definitely inhibits the reuptake of dopamine but it also inhibits the reuptake of serotonin and norepinephrine as well.
