I hope you tapered down your dose? Other wise you're likely going to go through withdrawals..
I say two weeks, at a minimum. You want to get the drug fully out of your system and spend a week or more getting used to being normal (not medicated) again so that you don't risk any complications.
The longer you wait, the better.
I would recommend against 5-HTP, we don't really know what's going on with your serotonin receptors now and if you just try and shove 5-HT precursors in your brain, Serotonin Syndrome is rather likely. At least at this stage of the game.
I say skip the 5-HTP, wait at least 2 weeks, a month would probably be better, and take a 125-150mg dose and nothing more after that. Always better to be safe than sorry
