I know what you mean. Less caffeine / nicotine helps, and maybe you should try some Kava Kava or Passionflower (if you don't want to take meds). Diet and exercise can go a long way, too.
I never really try caffeine or nicotine, so that's a plus I guess. I'll look at Kava Kava and Passionflower, I don't want any medicine. I was never on a diet, but I never eat much, so I don't really need it. I can't excercise much, because of tachycardia. Thanks for the help!
Edit: Kava Kava and Passiflower seem to be bad for me. I don't want to get more calm than I am. I'm too sleepy and tired already.
