Hi. I am on 2700 and worked up from the 300 like you are at. Did your doctor lay out a plan to increase? Each increase is ruff on me where I feel out of it and dizzy but the side effects lessen after a few days. I am on other similar meds like Cymbalta too so at this time I am not sure what is working and not. Right now I am in a flare up which is turning into more then a flare up so at one time I thought it was working more. Everyone is different in how they respond to meds. Hope you feel better
