Day or two, week or two, month or two.. whatever man, it's all relative depending on how much you've done in the past... I'm not trying to be judgemental or anything however really consider why are you even doing this to yourself. Perhaps it's still novel to you, maybe you need to go through this to figure it out that its not worth it, idk. Forget about listening to me, a stranger on the internet who may or may not have your best interests in mind -- LISTEN TO YOUR BODY and what it tells you, if it feels bad at the comedown thats not just because you did too much its your body healing and telling you that youve poisoned yourself... idk dude I wish you all the best, I'm deleting this thread from my bookmarks, I can't deal with comments like your last one anymore, it just drains too much out of me to be able to even consider trying to be helpful with situations like yours in the first place.
