The first side effects are mental, you also get physical side effects like body aches. I'd rather never experience that level of anxiety ever again.
I'm basically asking, do you think once every 2-3 weeks will be an issue? I think something about relying on it, even at 2-3 weeks, might make it an issue long term. But I'm not sure.
It doesn't affect me the same way as it did 10 years ago when i first tried. Back then it was euphoria and now it's just slight concentration. Which is ideal for working. But the euphoria is mostly gone.
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.
