I've been treated with so many different medications over 34 years that one thing I know is that next month, there will be a new drug that just might solve your problem. Keep up your conversations with your doctor and keep asking for help. My meds have dulled my senses and concentration for sure but I have grown used to the effect and am not attempting the kind of stressful exercise compared to you. Please don't give up.....I believe there is an answer out there for you soon.

PS: There are drugs usually prescribed for narcolepsy which, when added, help a great deal. I cannot remember the name of at the moment but they do help counteract some of the other side effects.
