Geesh – I had a reply all ready to go and Poof! It disappeared! OK – I'll try again 🙂
I have not read anywhere that Gabapentin (specifically) caused one to experience this, but I did read that some medications can cause it. I began to increase my dosage about a month ago, which kind of coincides with the appearance of the odor – so it seems reasonable to try to rule out the meds as a first step.
Initially I only smelled cigarette smoke once or twice a day and I thought it was my brain finding a new way to signal a craving. (I quit smoking in April.) But over the past few weeks the frequency has really ramped up. It's hard to guess, but I would say I now smell cigarettes between 50 and 100 times a day. Sometimes it's only during one inhale – sometimes it lasts longer – constant through many inhales. I've never really tried to time it.
I noticed some very small unusual movements when I first started taking the Gabapentin – like a tugging at the muscles in my upper arms/shoulders. It's nothing anyone else could have seen as it was ever so slight, but I was aware of it. I still experience them a bit but definitely less than in the beginning. However, since I'm taking meds that act on my brain, it didn't strike me as unusual. Other than that, I haven't noticed anything terribly unusual – although I will watch.
As for doing anything different – no. The pain in my feet came back with a vengeance when my brother died (Nov 15th), and despite increasing the Gabapentin I haven't been able to get that pain back under control. Other than that, it's been Christmas, which has been very quiet and peaceful for us this year, so it's all been good.
