Dear Eva,

I can speak to you about the great effects that I have had on stimulants throughout the years. Clearer, crisper, sharper mind, wide awake, etc. Those that I have taken are: ritalin, long-acting ritalin, dexedrine, adderrall and the rest of the lot. All of them have been very helpful. I would at least give them a try. Good Luck and Take Care.
