Adderall and definitly

I started taking adderall xr 20 mg about 6 mo. ago. I am 31 and was 185 lbs @5'11". It definitely raises my focus and I get more done at work. I lost 20lbs. and when I went to the gym to work out last week I could barly bench 135 when I used to work out with 190 or more. This tells me it is very tough on the body. My friends think I look like I am on crack. As far as the addiction thing goes it is true. If I try to take a day of I simply cannot function. It is not a insatiable craving when you don't have it. It just puts you in a major fog. For example, if you drink coffee or cola and you skip a day and are a little off you can still get by fine. If you skip a day of(or try to skip) adderall xr it is litteraly 20x worse! I plan on tappering off for good soon. I will find a better way to deal with my add. My main reason for posting this is to say: DO NOT GIVE THIS DRUG TO GROWING CHILDREN. I believe It will definitly do permanent harm.
