I am prescribed Gabapentin for Fibromyalgia, and my GP felt it would also help with my severe anxiety disorder. I only take it as needed at 600mg every 8 hours. My anxiety has been completely out of control lately, and I took it earlier today to see if it would help. I noticed a marked improvement anxiety-wise, but feel as though I am in a complete daze. I went for a long walk and noticed that I felt like I was floating, and that my brain was functioning properly when I was interacting with people at the store. I have recently been diagnosed as anemic, so this could be the culprit for the some of my symptoms; including increased anxiety.
Does Gabapentin cause one to feel as though they're in a fog and really out of it?

".... my brain [wasn't] functioning properly". Case in point, I suppose:)

Different strokes for different folks all depends on Brain chemistry
I felt that way when I first started taking Gabapentin. I was put on 300 mg three times a day to ease withdrawal symptoms from a prescribed benzo (klonopin.) I am a nurse, and took the benzo as directed but my brain still became dependent on it after 6 mos of regular use. Withdrawal from benzodiazepines is pure hell. I lost 25 pounds and half of my hair in the month it took me to come off the klonopin and I wanted to die every day. Gabapentin helped with the symptoms because it is like a "light" benzo which still messes with your Gaba receptors. But I dread coming off the Gabapentin now, some have miserable withdrawals from it also. I would never have taken a benzo or gaba med if I could go back in time. However, it can be quite effective for nerve pain. I was suffering from anxiety, and not pain. For anxiety, I would think anyone would be better off using meditation, therapy, rx ssri's, Magnesium, whatever you can to avoid Benzos or gaba. Good luck to you and your health journey.
I was recently put on gabapentin for fibro pain. Seemed to work good for a few days then started making me feel so drunk I was bouncing of walls and furniture. My brain could not process things and I was losing consiousness while eating. My face would literally fall into my plate. After someone woke my up it would happen over and over. Can't even function to do normal everyday things. No way I could ever drive. Has anyone else experienced such sever reactions?
I just started gabapentin, yesterday, took one, took one today. It's 5 o'clock and I just woke up and feel like I've taken LSD or something. So, so weird. I feel like I'm in an alternate reality, like it's weird looking out of my eyes... Yes, very, very floaty and just WEIRD!
i am in a constant state of confusion-i suffer from memory loss... anxiety, severe mood swings. i’ve become more and more withdrawn. i never thought it could be long term effects of gabapentin-i’ve been on this since 2011... i’m making a dr’s appt asap. is this reversible??
I started out on 300 mg Gabapentin 3 times per day. I had problems with it making me feel this way. 1 month later the nurse practitioner bumped me up to 600 mg 3 times a day. I still experience floating, fog, confusion, and it puts me to sleep. I have been on it now at the 600 mg level for about a month. I am having problems with neuropathy from Diabetes Type 2.I still suffer from pain but it does ease up some.
It does sound like anemic symptoms more so than gaba, and like Chuck, I wonder why it was prescribed as a "take as needed"... Unless you have already tried xanax, or other take as needed anxiety med. As mentioned, GABA is a long term nerve pain med not a take as needed. I'm very sensitive to meds, so it takes weeks to adjust. I take 800mg 3x daily for nerve damage, not nervous anxiety. I take xanax for that as needed. Hope that helps. Love, Suz.
I am wondering as well if gabapentin is causing me to get an increased number of headaches and maybe even sinus pressure. I'm also pretty sure it makes me dizzy and my blood pressure and pulse are fine, for example just now 138 over 77 with a pulse of 70.
I had problems with it as I was at full dose while dealing with shingles. This disease causes nerve pain. I got brain zaps, really what it felt like, jolts of electricity through my head. I felt confused, listless and like I could not concentrate, it did help the pain and I gave it up after I could tolerate the nerve pain with numbing the area and my Vicodin. I know someone who has been on it a long time and she says those side effects go away after a few months and it does help her nerve pain. I felt dumb on it. She is brilliant and remains so. Seems to be different for different people.
Thanks for the response. My Papa had shingles in his late 80's, and was suffering terribly, He couldn't tolerate Gabapentin at all, so went med-free. He always prided himself on not taking any pills right up to the ripe age of 92. I had thought that it didn't cause any cognitive impairment, so was surprised that he forwent it. Now I know what he was dealing with.
I, too, feel really "dumb" on it... I don't think that I could function at work whilst taking it which is frustrating because after seven years of severe Fibro and IC, I am finally somewhat in remission and ready to re-enter the workforce. It works like a charm on nerve pain, so am not sure what to do. I was hoping that this was a pain med that was relatively benign in terms of feeling "high", which is not a feeling I like.
Argh! Chronic pain is a real pain in the neck -- pun intended!
Love and light... S
EP = once again you are so right - Gabapentin is different for different people. My pain doc prescribed 300mg, 3 x a day, immediately after diagnosing me with Fibro. After 4 months with no change in pain level, I was increased to 4 x a day. Although there are times, far apart, that I feel my thinking is "off", some call it fibro fog, I really don't feel anything from it, good or bad. This "high" I read about others having has never happened to me. It may be that I am on so many other meds for other medical problems, I don't know... We all really are individual individuals.
Hi. I thought serendipity mentioned an interesting thought people have. Though dealing With shingles pain for ten years sounds brave, it sounds like a poor choice to me. The reason is that pain diminishes the enjoyment of life and leads to depression. As there are other choices, such as lidocaine patches, I am sad he suffered so long. I did take the gabapentin during the worse pain. Once the patches helped I stopped using it. I am willing to try something to see if it works. Then I decide from there. I never felt high on this. Brain zaps are not getting high. It is a weird involuntary shudder of body and feeling as if one got a small electric shock. Unpleasant to me. I don't tolerate opiates well, which might make one high. I have found that real pain is put in the background when using Vicodin. It is still there, but I ignore it easier. Meditation does the same thing. The latter is both free and highly effective. Most importantly meditation is not addictive. :-).
So glad to hear the fog goes away after a few months. Have been on it for 3 weeks, 300 mgs.at bed time. Taking it for tn. Causes a lot of dizziness. I work a full time job. I had just decided today not to take again but after reading comments will continue. Have helped with shooting pains but still have some constant ear pain
HI, I been on gabapentin for a few months now, after a few days I to feel like that I was in a fog. I was on 300mg 3X daily. After about a week or so everything was fine no more foggy feeling. Like the others said this isn't a as needed med. I'm now on 600mg which it toke a few weeks to get to this level. I would call my dr. if I was you. hope everything work out for you.
Thanks! My GP prescribes it "as needed", so I am a tad confused... I will definitely talk to him about this at my next appointment. Looks like even doctors make mistakes sometimes!
It sounds like your dr doesn't understand fibro. There is no such thing as as needed because you need meds all the time. Fibro doesn't come and go.
As KM stated, you can't just take this medicine as needed. It takes time to build up therapeutic levels. Not everyone takes the same dose. I went through 7 dosage adjustments before I found relief. Everyone is different and reacts differently. I hope you will see your doctor and get on the right dosage. Best wishes.
Seeking peace,

I have fibromyalgia as well and am on the same medication. I'm on 300mg and have to pick up my increased prescription. I think you're to high on the dose just starting out. I did notice a floating type of feeling when I first started but now I feel fine.
This is the problem, its not a drug to take as needed. It won't do much that way and your body isn't getting used to it. Those side effects don't last long if you're taking it regularly. Also you shouldn't start out at 600. The dose should be increased gradually. I don't now how you could tell when it's needed with fibro I have it and I hurt all the time.
