i went to the Cardiologist twice. Ekg picked up one palpitation but otherwise normal. Did a sono and a stress test. All normal. Actually while I was on the treadmill for like ten minutes running I had no palps. Internal Medicine doctor thinks I have clinical anxiety. Addictions counselor has no idea what is happening to me. Monday I go to see a Endocrinologist. I already had my thyroid, CBC, metabolites,and other blood test. Other test like, lyme, rheumatoid, Vitamin b screening, among others. They all came back normal. I also just went take a urine test today to test the cortisol and adrenaline levels in my body. I have not wanted to take the beta-blocker because I have thought that I could outlast this whole thing. I really deep down believe that this whole thing is caused by the Ultracet withdrawal. I mean the way I felt immediately after quitting would be too much of a coincedence to be anything else but withdrawal. THe short times that I do not have palpitations I have these feelings of anxiety come over me. Now one would think that it is anxiety that the palps will come back but it really isn't. At this point, I really expect them to come back and I do not really struggle over that part of it. The only relieve I get is thru exercise and I can't do that because as of yesterday morning I started with a cold. Freaking insane. If it wasn't happening to me I would think that it is craziness.
