So I'm 25, I have SEVERE anxiety issues, panic attacks, and I was on anti depressants for 3 years. My doctor then decided I was "happy" enough to go off them and he began me on treatment for my ADHD. I am on Adderall XR 20mg a day, and Xanax .25 as needed (I have been on xanax for years). I started the Adderall about a week ago, and completely lost my appetite, which my doc told me would probably happen. I have had a ton of trouble getting to sleep at night (no luck without taking a xanax to help), and it seems like if I have ANY caffeine I get SUPER jittery, anxious, and two days ago I made the mistake of trying an energy drink, which basically gave me severe muscle spasms and shot my heart rate through the roof (yay for Hospital visits... ). I'm about 140 pounds, and I'm not sure if my adderall dosage is too high for my weight or if I'm just not adjusted to it yet. I guess my question is if the side effects (jittery, increased anxiety, insomnia) will decrease over time, or if there is any way to lessen them? Any insight at all would be super helpful! Thanx!
