Re: Adderall not working!
I am actually 17, and taking Adderall IE capsules, and to be perfectly honest, depending on your body size, weight, metabolism, ect. 20 Miligrams is almost nothing if you are on the larger end. I started on 30, and it had very little effect after a week of normal consumption (But if its Adderall instant release, prolonged consumption does not really make a difference anyways), so it was even doubled to 60 MGs, which works great. So its more than likely that you really just did not take enough to have a profound effect.
Adderalls effect really should only rely on how well your body can metabolize or use it, and people without ADHD can easily take it without effect as well. IF you had any significant amount of Citric Acid, Vitamin C, ect. Even so much as a glass of orange juice shortly after consumption, it would also greatly dampen the effect of the Adderall.
The big part of what you said is that you still eat as you normally do. Lack of appetite is one of the most common symptoms with stimulant drugs such as Adderall, although I guess it is possible for you to have a normal appetite. But to me though, I really just think you did not take enough for it to actually do anything major to your body. Just make sure you have ADHD first though, get the drugs yourself if that is what the doctor has ordered, and the fact that the pills did not work is in no way a sign that you have it. There are just so many other contributing factors at work to determine how it will effect you.
I hope this is what you were asking...? If not... I did not take my adderall today, so I blame it on the ADHD. ;P
