I would get lightheaded sometimes before taking the Paxil all of the time. Never enough to interfere with daily activities, but annoying just the same. When I was given the Paxil every day for the fibro, the lightheadedness went away. Well, I'm now being weaned off the Paxil because I feel fine without it. I currently take it every other day and I'm fine. The problem is the lightheadedness returns when I'm off the Paxil, but only after I have a normal dinner. Is this still the fibro or could it be something else, like my thyroid? I don't have any weight gain or loss, but I'm always tired and thyroid problems run in my family. Any suggestions?
