I've been noticing along with the other typical side effects like pins and needles, bad taste, no appetite that are normal with this med, and also subside for me for the most part after a few weeks, I also get really bad headaches. Which is ironic being that this is why I am taking it in the 1st place and one the initial side effects all wore off that first 1 week-10 days my headaches have been great but, as soon as I increased my dose the same headache is back. It's hard to explain but, it's not my normal everyday and yes, I mean everyday headaches. Has anyone here experienced this just with an increase???
