What are the side effects? I just started on the Gabapentin & I started with a 100 mg & it didn't help so it was increased to 200 mg & nothing so now I am on 300mg & I don't want to take anymore. I heard this is a hard pill to get off of if you have to. I take 200 mg at night & 1 in the daytime. Once the drug gets in your system it is easier not to be so tired bc at first I was real tired & sleepy. That is why they said to take it at night & 1 in the day to take away some of the pain. Is this a pill you have to keep on increasing? I also take 60 mg of Cymbalta which helps me to cope.
