Please be very careful with the Xanax! If you have been diagnosed with anxiety or panic, talk to your doctor about putting you on a long term antianxiety med like Klonopin. Xanax is really best for very short term, PRN (as needed) use, not long term treatment. Also know that while meds are extremely helpful in controlling the symptoms of anxiety and panic, they are NOT a cure. They just mask the problem. Therapy will get to the root cause of your anxiety where you can confront it, deal with it and recover. Meds help during this process, but without therapy, you're just looking at a future of drug dependancy.
And please, NEVER increase your dose of ANY psychotropic meds without consulting your doctor.
Peace
