I experienced lots of side effects, including:
Rapid heart rate, palpitations, and chest pain (leading to several trips to the ER)
Air hunger (just found out there was a name for this)
Insomnia
Sweaty palms
Ice cold hands and feet
Hair loss
Dry mouth
Teeth grinding
Gum recession
Joint pain
Muscle tension
Dry eyes
Frequent urination
Twitching (particularly the eyelid)
Weakness/fatigue (after extended use)
Inability to regulate body temperature (too hot in summer, too cold in winter)
Appetite suppression
After years on Adderall, I starting thinking this was normal...
