For this I'd call a pharmacist. Alcohol often causes anxiety in people prone to it because it causes disorientation much like that we feel when we're anxious. And remember, you never have to go to a hospital for an anxiety attack -- they do pass, though they feel awful when you've having one.
Well, yes of course I wouldn't go to the hospital for an anxiety attack alone. But a heart rate over 200 for almost an hour is very dangerous. Thanks for your advice
I guess I should have said, a lot of people on this site are constantly checking their heart rate. This is an obsessive behavior, as the heart rate varies a lot through the course of the day. During exercise, people intentionally try to get their heart rate up to strengthen the heart long-term, and most people just don't go checking their heart rate unless they've had a heart attack. You also said you've been to the hospital many times because of anxiety attacks. I guess what I'd ask is, have you ever been in therapy with a psychologist who specializes in anxiety treatment, such as a CBT therapist, who can also teach you many relaxation exercises such as breathing exercises and meditation that might help to lessen some of these physiological symptoms even if they don't end up solving the underlying anxiety problem.
