I guess my cautionary tale is, how does the OP know she does NOT have heart disease, given her family hx? Up until my DH was on the table for the angioplasty, no one believed him (you ride 4,000 miles a year and you are thin). I am sure the blockages were there long before the symptoms. I am not advocating she get surgery, but if she wants to stop the drugs and try something like niacin or Metamucil, I would get a stress test with IV contrast dye, to rule out anything. I tend to want aggressive treatment for anything, and heart disease scares the crap out of me. Enough to keep me on the straight and narrow in terms of my eating and activity.
I totally agree that people want a pill to fix everything. It is difficult to believe the amount of non-compliance I see as a therapist, and not just with psychotropic drugs. I mean compliance with all medication.
