Thanks, ya'll. It didn't keep me up last night - in fact, I think I slept better. I took one this morning and will probably take another one soon - I'm not doing any driving today. They do tend to make me a little woozy. But my pain level has increased a lot here lately - I'm very achey in all my joints (hands, wrists, knees, elbows, ankles). Almost like arthritis. I go for an MRI on Tuesday and then will have an appointment with the Neuro soon after that so I'll see what he says. I hate the "doped up" feeling but it's either that or be in pain.
