I take .25 mg of Xanax 3 times a day and it does help with me not caring so much about the physical symptoms of the anxiety. I, like you, cannot tolerate antidepressants - cause heart problems. I deal with the anxiety every day and am in the midst of trying to find a way to cope with it without other medications. I know this does not answer your question about how to deal with it but I just wanted you to know you are not alone.
Checking in to see how your doing? What about Dramamine or one of the OIC meds for nausea? Of course you should discuss the use with your physician.
Take care and keep posting.
