Oh, Scott, I am so sorry. Thank you for your response. We are not alone, but I am sorry that you are also going through the heart issues.
I am with you about the SSRIs. The thing is that I have been on/tried most of the ADs. However, I was on Wellbutrin and Cymbalta the longest. I was on Wellbutrin for about 3 years and then was on Wellbutrin + Cymbalta for about 6 years. I think that I might've gotten too much norepinephrine (since they both contain norepinephrine). I started having severe anxiety/palpitations last year and wanted to stop both drugs. It was easy to stop the Wellbutrin, but not the Cymbalta (of course). I really think that any of these drugs have the capability of causing anything. Unfortunately, I have not been able to be without them for about 10 years (either they made me worse and I still need them or I got worse on my own?) But, your suspicion about the heart issues is most likely true.
However, my p-doc said that my anxiety increased. And, that my depression and anxiety feed off of each other (so my depression increased too). I asked him if ADs (any of them) could change your brain (in a bad way) and increase your anxiety/issues. I never felt such anxiety/palpitations. He said that would be "bizarre" if ADs changed your brain. He also thought that I could wean off of Cymbalta in a matter of a couple weeks by taking some Prozac --- HA!!! My anxiety went through the roof!!! Very scary. He's supposed to be the expert. Well, the thing is that they don't really know how any of these drugs work exactly -- which really scares me. I am so sick of all these drugs and their side effects --- and a medical community who don't really seem to know what they are doing. Also, I know what you mean about the side effects, I get most of them myself.
The $$$$$ is in the drugs, doctor visits, etc. It's not in finding a real cure for these issues. I realize that the brain is complex/complicated, but it is 2010 --- you mean to tell me you couldn't have made bigger strides by now?? The brain is only the most important organ we have (they are all important, but you know what I am getting at). Sorry, I am on a rant.
This is why I am researching alternative methods/procedures -- like in my post above. It scares the hell out of me to think of using anything to "shock" my brain (whether it is invasive or not, mild or not, but especially if it is invasive/strong). But, I am starting to get to the point that I want and need to know more about these other options. None of these ADs have helped me fully. And, they all have side effects that don't agree with me. 10 mg Celexa seems to have calmed my heart down, but not completely, and I don't want to just keep increasing.

I also feel kind of "out of it" and "flat" on it, kind of like a zombie. Low-dose Klonopin seems to help my heart, but I don't want to keep taking/increasing that either. I am starting to feel willing to take the risk of one of these procedures, especially the rTMS (transcranial magnetic stimulation). However, my p-doc said that procedure hasn't been around long enough/they don't know enough about it. I am trying to find people who have had this done (or any of the procedures, really). Please let me know if you hear/know anything about these.
I wish you health and happiness - Hopefaith
