Ugh, yes on the headaches. I take it at night and at seems to help since most of my headache is during sleep. By noon it's lessened to a dull pissy ache. It was the worst at 75 to 100mg. Now I'm at 200, the headaches aren't as bad. I think they are suppose to go away as you adjust to the meds. If not, I'd talk about getting a new med.
