I have had nausea and loose stools for the last couple of months. I just don't feel right. I am tired all of the time and really don't feel like doing anything. I feel like I have a headache more than I don't. I have been treated for migraines, but these are not migraines, just annoying headaches. I am being treated for depression with Zoloft. I have always had an issue with weight which has ranged from 118 to 260 (my largest, I didn't get this big in either of my pregnancies) over the last 25 years. I am extremely obese...43...5'4"...260 lbs.
