Adderall and chest pain

Adderall has been an excellent drug for the treatment of ADD. It took me from a lethargic, disorganized adult, to a more productive one who finally could finish her work and leave her desk organized at the end of the day. Unfortunately...
...there are many side effects to this drug which has, reluctantly forced me to quit taking it. The weight loss was a welcome side-effect as was getting rid of the lethargy I have experienced on a daily basis since the age of 11 (anti-depressants did nothing). However, my infrequent migraines became daily and excruciating after starting Adderall and its generics. My insurance could not keep up with the coverage of the migraine meds I needed. I began experiencing ear problems (primarily in my left ear) that felt like I constantly had the pressure associated with a cold. After visiting my doctor (who told me nothing was wrong), an ENT doctor, getting a hearing test, and an MRI of my ear canals and Eustachian tubes, I finally found out it was due to the Adderall. The worst side effects, however, was a gradual increase in dermatitis (dry, itchy, scaly, skin). My complexion looked sallow and my back and neck broke out in horrible cyst-like acne (not typical AT ALL for me). My eyes became so dry (not to mention the cotton mouth), that I began trying to reverse this effect with pills from a Lasik eye center (helped, but didn't solve the problem). Perhaps the worst side effect, however, has been the hair loss. Long, beautiful blond hair, has been replaced by very thinning hair (comes out tons at a time in my shower), which is now brittle and breaks all the time. I have finally decided to quit this medication despite its benefits. I only took 15mg 2/day. Once my body recovers, I hope to take on an as-needed basis for important work projects or hectic weeks where productivity is necessary. Other than that, I won't take it any more. The side effects are too severe, even for me.

I am 21 years old and my doctor prescribed me 20mg of Adderall to take twice a day. I've been taking it for about a week (only in the morning, I'm still too wound up to take it 4 hours later!) and I have already lost 10lbs. Also I've been having trouble breathing deeply, chest pain, tingling in my arms and legs, and no appetite whatsoever. Are these symptoms normal?
