I take Neurontin and it has been a LIFE saver for me. Yes, I did have some problems with drowsiness for the first couple of weeks or so, but that subsided rather quickly, and when my doctor got me titrated to the right dose, I noticed a world of difference in my nerve pain levels. This is a medication that takes a bit of time to find the correct dosing, and also takes some time to build to a steady level in your system, so please don't be looking for instant results, because it won't happen.
As far as the sweet tooth, I had that problem with Lyrica. I've never been one to have any kind of sweet tooth, but that Lyrica gave me one and I gained several pounds in the month or so that I was on it. I'm not on it anymore because I can't handle the weight gain- it's just not for me.
I have to admit that I was scared to try the Neurontin at first, but I also realized that it would be such a shame that something that could possibly bring me some relief was right there, but wasn't given a fighting chance because I was affraid to take it. Your doctor will start you with a low dose, and then titrate you up, so please do give it a try. If it's not a fit for you, then there are other things to try, but you won't know unless you give it a chance, ok?
Take care guys, and I do hope you will get some relief with it. For me, it's been a life-saver for sure. This is just me though....
