Hi all – I would love any shared experiences on using muscle relaxants. My doctor is having me try them as preventatives. My problem is they seem to give me horrible heartburn after a week or so. I have tried Tizanidine, then Soma, then Flexeril (makes me feel a little too weird/tired/buzzy the next day), now Norflex. My doctor said it was unusual to give me heartburn but I would stop taking them, the heartburn would go away, and then I would start again and have crippling heartburn. They don’t seem to be too bad in general but I still have a headache pretty much every day (I am also on Botox) and migraine 1-2 times a week.
