So here is the upshot on my Neurontin/gabapentin usage and tinnitus. You can catch my earlier posts on this topic up higher on this thread and on this one: https://www.tinnitustalk.com/threads/why-do-doctors-say-tinnitus-wont-hurt-you.10831/#post-140708
Anyway: I just stopped taking Neurontin about a week ago. I started taking it around July 9, under my internist's supervision, for severe shingles pain. She worked my dosage up to 1800 mg daily, which I reached around July 19. I then stayed on that dosage until Sept. 8. Initially the drug made me feel pretty out of it but I built up a tolerance to the side effects quickly. And yes, my tinnitus definitely was quieter under the drug. Probably dropped from daily highs of about 5-6 to about 2-3. I would have some moments where I could barely hear it.
BUT: In early September, I suddenly starting feeling very weird. Disoriented, dizzy, feeling I was outside my own body. I sometimes would wake up at night and think I was not in my own bed. Asked the doctor if this could be related to the Neurontin and she said probably. So we started backing off on the drug slowly and I quit it completely last week. The disoriented feeling has gone away. And yes, my tinnitus is back to its former levels.
I experienced some anxiety symptoms while withdrawing. And my sleep, which was great under Neurontin, has now deteriorated again. But I was able to handle the anxiety without medication. And disrupted sleep has been part of my life for almost 15 years, long before T, so nothing new there.
So, is Neurontin worth it? Not for me. I believe this med was seriously screwing with my brain. The literature shows some people become suicidal on Neurontin. If you want to try it, you definitely need to do it under a doctor's care, increase your dosage very gradually, and cut back the same way. Also, many people here at TT have reported Neurontin did nothing for their tinnitus. But I believe in my case, it did tamp down the noise.
Also, everyone's reaction to this and many drugs will be different. I believe some here have reported no side effects from Neurontin. This just was my experience.
