Hi ....quick question. I have been on Flexeril for a few months now, after a Fibro Dx. I always asked about weight gain with anti-depressants, but didn't think to ask with a muscle relaxant. The muscle relaxant Flexeril is working quite well for me. I take two each night (one does nothing for me). I am beginning to wonder if Flexeril is the cause for some weight gain....never been a problem in the past, and is just accentuated now by a less active lifestyle, but I feel like the gain was pretty quick. I have taken Soma in the past for back injuries, and I am wondering if it may be as effective as Flexeril and of course, hopefully without the weight gain. The only meds I am taking is this muscle relaxant and that seems to be okay for now, keeps pain at a minimum and I do notice a difference with getting better sleep. Would love to switch to Soma if it would be as effective without the weight gain. If anyone can answer, please share. Thank You.
