Alcohol and any stimulant are not good tummy mates, or for that matter, body mates. I don't know about your other problems with your breathing or anything like that. I haven't heard of that being a side effect, and have never experienced that after I have worked out on it. I do not exhibit any of the problems you have told us about when you work out. I am concerned enough about how you are doing after you work out that you should talk to your pdoc and see what may be going on. You might do a Google search on Concerta and find out what the pros and cons are being on this stimulant. Armed with this information, you can better talk to your pdoc and ask her/him if concerta is the best thing for you. Good luck for finding the best combination for you.
