Gabapentin
"I was prescribed this medication by my PCP for my fibromyalgia in Feb 2016. I should have known something was wrong when I gained 7 pounds in about a week &/a half & I wasn't experiencing much pain relief. I continued to take it. The doses would need to be increased often & I was up to 900 3x/day. I took it for over a year &  was taken off of it when Lyrica was started. Lyrica didn't work out due to adverse effects. I recently started this again & I've gained 6 pounds in less than a week. I've been extremely hungry so I've been eating more, even though I'm trying to lose weight. This medication has also made my pain/brain fog worse & when you have fibromyalgia, you don't need that getting worse. Never again!"
