Mark, did you say you still drive a tractor-trailer? I used to be a truck driver, but my counselor suggested I quit (even though I didn't start having PA's until AFTER I quit driving). If you don't mind I'd like to ask you few questions about your driving. DO you have the attacks while driving? If so, what do you do about them? I still have my CDL and would love to drive again, but my counselor suggested against it. Any help would be greatly appreciated. Thanks.
