So I haven't been on Adderall, but I have been/am medically obese. I started these forums at 244lbs, but my highest has been 260.
First thing I would say is that not every day is going to be a loss on the scale. A faulty scale is also the devil, I'd get rid of it if you think it's faulty. If you find that your mood is completely ruined when you don't get the numbers on the scale that you want.. also get rid of the scale, it's probably doing more harm than good and you'll always have doctor visits for weigh-ins, or you could get measuring tape and actually take measurements as opposed to weighing in.
Everyone is different, and everyone is going to lose at a different rate. We retain water differently, and that can mask weight loss sometimes.. and then you can get what people refer to as a "whoosh".. or a sudden drop. One thing to consider too, is that your body is likely in starvation mode if you've been eating so little and exercising so much. That can make weight loss take longer as well. It may benefit you to either reduce exercise, or increase calorie intake.
Slow loss also isn't bad. It may be depressing when you're focused on just the weight and all you do is look at the overall picture though. I lose 1lb a week. If I look at the overall picture of how much I have to lose (over 100lbs) then it's very easy for me to go "gee, that's going to take two years" and then get all mopey. So what I do instead is focus on lots of tiny mini-goals. A goal can be something like staying on plan for a day, or a week, simply not regaining what I've lost, losing a certain (small) number of pounds, or even just making one healthy choice a day. This way not only are things much more in my grasp, but there are lots of little things to celebrate which makes the ride not all about weight loss, but more about health and enjoyable overall.
Hope some of that helps, and welcome to the forums!
I've only been here two months.. but it's been my longest attempt to get healthy and I really think it'll stick. I've committed to a lifestyle change, and not just a diet to get down to a particular weight.
Just as a point of reference, I'm gonna link a few daily weigh-in threads that I participated in for September and October. If you find my post you can see my weight fluctuates a lot, and a lot of times the scale will show an increase.. but overall weight is still decreasing.

Anyway.. stick to your plan, eventually the scale will start to move (also get a new scale !!) You can do it
