Well I survived day one of the pre op diet, but not without developing a KILLER migraine. Usually I can sleep a headache off, but not this one! I got it yesterday afternoon and its still torturing me now. I've also starting feeling very dizzy and faint. I just don't know what to do. I can't take any pain relievers because they're blood thinning. I'm waiting to hear back from a nurse at the weight loss center now, but I was just wondering if any of you had any advice in the meantime.
