I had already gone from 250 lbs to 215 before taking Adderal. I went from 215 to 175 way too fast (4 months) once I began taking it, didn't even notice how much I had lost until one day I happened to get on a scale. I am 6'2" tall and have generally a large build. People thought there was something wrong with me. It scared me. So, now I make sure I eat early in the day and often. I take in a lot of calories before I take Adderal in the morning. I have to make myself remember to eat during the day, because the urge to eat is not always there. I usually eat a good dinner. By paying attention, I have increased my weight to 185 in about 45 days.
It's very nice to think I will not be fat again anytime soon, but losing too much weight is dangerous and I let it happen without noticing. I think when I was overweight I got in the habit of not looking at myself too closely in the mirror. And the idea that I could lose too much never entered my mind. When I did take a good look I realized that I looked awful. I looked better at my heaviest.
Adderal has caused a wonderful change in my life. I don't know how I managed before. I can listen, prioritize and actually concentrate on a few things at a time instead of a hundred. I don't think I'll ever think about one thing at a time. I can't really imagine it, but frankly, it is entertaining to be able to think about more than one thing at a time as long as I'm actually completing what I have to complete.
My Doctor weighs me in once a month now and if I fail to keep my weight up, he may reduce or eliminate the medication, so I have that for motivation as well.
Good luck to you.
