Why do I always: Tap my feet, bounce my legs, tap my hands on the table, and chew plastic/ice/aluminum?

I'm a 24 year old, 290lb, 6'2, and Caucasian male. I was disagnosed with adhd as a child but never took meds for it. I mellowed out somewhat on the bouncing off the walls and whatnot but still have the symptoms mentioned above. I never took meds because my Father's objections toward Ritalin and such. But as an adult, what do you all think a doc will prescribe? I want something that will relieve symptoms but not stone me. Is there hope for me?
