I have seen several messages warning about Elavil and weight gain. My psychopharmacologist has suggested that Elavil might be what I need to get a decent night's sleep, and he says that at the levels prescribed for that purpose, weight gain isn't usually a problem. I'm not sure what the usual dose is for pain relief. (I know that some people don't seem to think it works at all for pain, but this doctor said he recently had been persuaded that it does, at least for some patients.) But apparently, the dosage needed for Elavil to do its original job as an antidepressant is most likely to cause weight gain. I've gained about 10 pounds in the last year (beginning before I knew I had fibro), and I'd like to be able to blame it on something other than myself, but I'm probably kidding myself. I just don't want to add to that anymore. So far, I'm just into the overweight category using the Body Mass Index charts, and I'd like to back out of that category and go back to normal rather that move further into it or into the obese category. For most of my teen and young-adult years, I waged the battle of the bulge, and it was always stressful, frustrating and generally a failure. I finally lost weight when I developed IBS and became afraid to eat--not the greatest way to lose weight! Don't want to go through any of that again. --Laura R.M.
