Haven't commented on these threads for a while, but have been watching (as my occasional like or haha reaction to posts will show), but re: rtialin, as I may have said before, I was prescribed it between the ages of 8 till 18.
I will say it definitely helped my concentration, but 1) I weighed 9 stone 8 when I left secondary school. I'm a ~5'11 bloke. That looks *very* skinny, and I had a ridiculously large appetite, and 2) by the end of that period I used to feel sick if I went a couple of days without taking it (I didn't usually have it at weekends or school holidays). I don't recommend that.
This post is not a comment on anyone else and is intended solely as a relevant anecdote.
