Right now I am at only 200 mg. Back when I took something like 900mg I developed problems with my legs and ankles swelling. So I changed to Lyrica at that time. Then when I got shingles the doctor put me back on gabapentin on a dose I’ve forgotten but I had no bad side effects. Since Lyrica made me gain so much weight I went back to gabapentin on a low dose and it helps a lot.
