When I first was put on Adderall XR in 2005, I was doing just fine - no worries , no side effects. Then just recently in Aug 2007 I have been experiencing the most strangest side effects ever on just 20 mg daily. They include pain in my jaw muscles, pain/aches on the sides of my face, anxiety, tight headaches near the temples, Pain in my joints , back pain, foot numbing and foot pains, cramps around my face & forehead. Constant sweating , feelings of anxiety from time to time, Zoning out, tiredness, mood swings: one moment feeling very happy and motivated the next moment feeling irritated, worried, anxious, sad and depressed ( hopeless). In addition I also get an increase in salivation and a constant need to lick my lips and clench my jaw/teeth, constant urge to take deep breaths. Has anybody out there ever experienced such side effects after a long term use of Adderall XR on just 20mg a day?
