Hi -
I can emphathize with you because I have also been told (only by my daughter) that I have AADD (Adult). If I were you, I would seriously consider stopping the amphetamines. I, too, tried those a long time ago before they were considered to be habit-forming. At first, I had lots of energy, but then I started thinking that I needed them to have any energy or desire to get work done - especially uninteresting tasks. But, fortunately, we moved to another state, and my new doctors refused to prescribe them. I then learned that I could get along just as well without them - or rather, that I had only thought they were helping me.
You wrote that these drugs aren't helping you either. Actually, I think that the amphetamines made me more nervous than I already was and that I really didn't get more done while taking them.
I was formerly a heavy smoker but quit 20 years ago after being constantly nagged by my children. I missed and still miss (although I have no urge to start smoking again) it because when I could look forward to a "cigarette break", it gave me a reason to finish cleaning, laundry, etc.
The only thing that helps me get things done now is knowing that I will have company coming - even a repairman or painters. I force myself to do just one big thing. You'd be surprised at how good you feel after you have finished cleaning out just one cupboard and throwing away things you know you'll never use or which are outdated, etc. For instance, you should finish cleaning out that walk-in closet. - just call your town dump or look in your weekly town paper for a handyman who will come and take your trash to the dump (the computers, etc.) Then you'll see how neat that one closet looks and it will give you hope and spur you on to do other chores. Take your time.
I, too, misplace keys. You didn't "lose" the keys - you probably put them down and then left the room and forgot which room you left them in. That is very common. My dad used to tell me that I would lose my head if it weren't attached to my body.

I was 10-years-old at the time.
Please try not to worry about ADD. I really think that some people are just disorganized from birth and some are extremely organized (i.e. my daughter).
Try putting only one thing on a list for the week that you must get done.
Necessary things like laundry (so that you have something to wear, etc.)
will get done somehow.
I hope I haven't been too unclear and that you can maybe at least know that there are others out there just like you - you are not abnormal.
Good luck!!!
