I started taking gabapentin about 3 weeks ago, I am taking 1800mg and it is working wonders. I am concerned however, about the weight gain and bloating. I took seraquoel at one point and I blew up 20lbs, plus other awful side effects. I lost the weight immediately after stopping its use. I am happy with the help gabapentin is providing me, but I am noticing some weight gain and bloating. I drink a fair amount of water throughout the day. What can I do to control this?
