I have read a lot of stuff about Addarell on different blogs and websites (think most of them might be true, it’s not an OTC drug btw, you need a doctors’ prescription for it), but since it’s not available where I live therefore I can only share my experience with what I had tried. when I took my first tablet of Ritalin 10 mg I stayed awake for the whole night working on an urgent report that I needed to present the following day, however, after that the consecutive intake of the medicine didn’t work so well for me, there wasn’t any excessive focus to start with, just a little alertness which faded away after the first dose and the consecutive doses were all a waste of money.
I think we should rely on natural adrenaline produced within our body through activities, so my advice would be to go to a gym or do jogging (any cardio exercise with doctors’ approval) et cetera.
Definitely there are medicines that do work which are either made illegal or maybe too expensive for us common people to use, elites, however do have access to them. Remember not all medicines work and most of them are just scams (legal or illegal drugs, big pharmaceuticals with deep pockets).
