matthew, age 18, ~156lbs, ~6.2feet, pretty darn fast metabolism ;-) - haven't really taken any add meds religiously before but have tired adderall xr a few times.

while walking down the halls, i noticed i was almost tingling(eg: the 'high' from add meds). i talked to people, i was calm. i didn't really feel that nervous, but then again i normally don't. i took an hour or so to fully kick in. i know i was able to concentrate a lot better. i wouldn't be a zombie or wasn't a fused bomb, or 'weird.' i was just normal. simple things did indeed seem easier to prosses with out getting overwhelmed. i could even concentrate on my school work and overhear a few stories my teacher was telling the class - and even some other kids's convos ~~ oh noe, i'm not sure if i want to be able to know what they're talking about. sometimes class didn't seem that long after all..., i ended up reading 15 pages of this random ender's book, and even though i have never read it i was able to keep paying attention. noormally after 6/7 pages i lose focus - even if i enjoy the book. i wasn't really sad, which is greaat...but i think it wasa kinda part of the fact that life was easier. it's 3:44 and i took 70mg around 7:45..., so around 8 hours. it's suppose to last 12 hours but i doubt that. maybe 12 hours but after 8 or so hours the drug will get weaker and weaker - at least for me. even though a lot of people asked me for help....i was less iritated since i could also get my work done - normally i'm a bit hesitant since if i help someone, then i may not get my school work done. i supppose i'll have to do my hwk right after i get home - in hopes that the big v will still assist me. i would consider this drug a bit more subtle.

i would say today has been a successful trial.

cons -- i didn't eat a thing, i ended up chewing the same piece of gum for at least 3.5 hours, and maybe i seemed a bit too clam.

your post interests me because i am considering a switch to vyvanse from adderall xr and (sometimes) a focalin ir supplement. the focalin gives me a headache, makes me sort of spacey, and totally wrecks my libido. the adderall xr works great, but it's gone by 3 and i really need something to help me through homework, work, etc. i'm a junior in college, so this is especially important.

i'm tempted by the rumors that vyvanse lasts a little longer than adderall, and i think my body would find this more agreeable than a supplemental dose in the afternoon.

do you experience any side-effects while on vyvanse?
at what time can you really tell that it's worn off?

thanks!
