I'm pretty familiar with the ol' mixed amphetamine salts (adderall), and I can tell you that 100 mg is a considerably large dose. I cannot fathom taking such a large dose; I think my heart would beat straight out of my chest and into the windshield, the computer monitor, my girlfriend, or... I don't know, whatever may be in front of me at the time. lol
No, but seriously, that's a large dose. I would think that 30 - 40 mg would put most people where they want to be. If that's not you, and you really do need to take 100 mg, well, then you can rest assured that you are most definitely
not ADD/ADHD. lol
