I have been experiencing strong palps ( I get atrial fibrillations too), as well as incredible anxiety. My GP prescribed 1mg ativan as needed...scared to take it. Before I unintentionally start a medical debate I will just remind everyone that unfortunately my case is not so cut and dry. Lupus along with pulmonary hypertension (high pressures in lungs), atrial fibrillation and polycythemia, complicate things, going for colonoscopy for inflamed colon plus caring for a daughter who had her large intestine removed at 11. I really like the natural route but it is proving tough right now. I was put on the lowest dose of lexapro a while ago. Two docs have differing opinions on that. One prefers the benzo route temporarily, the other ssri's, hence an increase. SSRI's can be vasoconstricting, and I take vasodilators for my condition! Am trying herbal means and vitamins as well. So question is...anyone have any experience with 1mg ativan? thanks all.xxx
