Hi Desi,
What you're taking isn't really a very high dose of Neurontin but it may need to be titrated a little more slowly.
I started low and very gradually took myself to 1800 a day. I did get all the fuzzy head stuff when I tried to start off at a too high dose but now I am well used to it and have no side effects at all.
Wishing you luck with sorting it out,
Love Tayla
