That is how I felt before I started Adderall. I am on Adderall XR, so just have to take it once per day. Maybe XR would prevent constant crashes? I have heard if you are feeling like a zombie, your dosage is too high, but I am no expert. I am just here to say that you shouldn’t have to feel that way! I don’t know how long you have taken the Adderall, but when I first started it I had major exhaustion crashes when it wore off and had a really tough time getting up in the morning. This lasted about a week or so and then I felt great. I did not feel exhausted during the day while the meds were working, though. I started at 10 mg and am now on 15mg. Hope you can get it worked out!
