It worked for me but I don't see how people can take the stuff for years on end.
The side effects were a problem.
Difficulty falling asleep.
Long, intense technicolor dreams every night. I would wake up exhausted.
It definitely helped my attitude during the day but it distorted my visual acuity in that every object had the most vivid, almost neon colors.
Then there was also a sexual side-effect as well.
I never felt addicted and simply had no desire get more after a few months of use.
These drugs are extremely powerful for adults and there's no way I would advise any parent to put their child on them unless it were a last resort.
Because not everyone gets the side effects, or if they do, it is minor.
