I came off Gabapentin last November because I'd put a lot of weight on. I spoke to my Consultant and he said that Pregablin didn't put as much weight on as gabapentin and I changed over to that. Well I persevered with it until last week, I'd gradually increased the dose until I was on the highest dose per day, 600mg, but the nerve pain was there most of the time especially at night. My GP has put me back on Gabapentin (at my request) as I couldn't stand it any longer. i haven't slept properly since November and I've decided that I'd rather be fat than in pain all the time. A lot of people told me that Pregabalin was as good as Gabapentin but not for me. Has anyone else ever tried to change from one to the other? I'm at the point now in the change over where I'm taking a very low dose of both and it's awful but neccessary.
