I am really struggling with weight gain on Pregabalin which I have to take for really bad neuropathic pain. In addition to this I have to take steroids for Addison's disease, which make me very hungry all the time. I know it sounds melodramatic but it's making my life so miserable. I'm not massively overweight yet and I could pay for a private prescription but my understanding is that I can't even do that until I am a lot more overweight. Is that the case?
