Yes the euphoria is the first thing to go, got to wait quite a while for that "magic" to come back.

I was using it daily for about a year or two, and it really helped but also caused issues with my personal life, relationship and so on.

I think you're probably ok, keep in mind it is a neurotoxic drug so you'll want to mitigate that, and your usage as much as possible, antioxidants, not overheating and that sort of thing.
