I’m on 300s of gabapentin, it can sometimes be a little sedating and if you take enough it can cause some fog. You may get used to it with time though.

I'm on 300mg 3x/day. I deal with daily fog every other day. I know lots of people who stopped taking it for their reasons due to brain fog. I keep taking it because I have CIDP and while I wait to start my IVIg I need pain relief and it's the only medication thats seemed to work in the mean time

I take 600 mg in the morning and 900 in the evening. It definitely made me feel foggy for a while but since I have gotten used to it I really don’t notice any side effects at all. I hope that it helps relive some of your pain and if not then that you are able to find something that works for you!

I’m on 400/4x daily so far. They’re using it off label to treat my anxiety but I find it can sometimes help my fibromyalgia? The issue is a lot of anti inflammatory medications don’t seem to help mine. So I experience lack of range of motion, fibro fog, & associated symptoms. But I’ve only been fully diagnosed for a year. It’s a process! You’ll get there!

I take 600 three times a day (total 1800) for anxiety and OCD. After initial side affects it has been nothing but helpful for me, as far as I’m aware.

I’m on 900 mg. I don’t get any of the drowsiness but I don’t get drowsy even with like Benadryl or other things that do. I have brain fog due to TBI but it hasn’t gotten any worse since I was out on gabapentin

I do get a fog outside of the high, Im prescribed 800mg for insomnia so that's the goal, but it doesn't get too bad unless I've been using weed as well.

I started at 100 with the goal to dose up and am now at 300. I take it at night because we knew one of the side effects could be drowsiness (especially combined with other meds). It’s especially helpful for my insomnia!

I take 600mg at night and 300mg in the morning. It did make me feel very foggy and sleepy at first, but over time I’ve gotten more used to it

I have also had more fog every time I take it!

My brain was so foggy I forgot where I lived. Couldn't even remember what my house looked like. Also all my mental imagery became distorted. When I pictured something in my mind is was all messed up. I quite taking it. I'd rather be in pain than not be able to think clearly.
