Ruby,

What dose of gabapentin are you taking? I have not heard of it being prescribed for head ache.

I take 900 mgs a hour or more before bed. It is really helpful at letting my body and mind relax. Otherwise, I am tense both mentally and physically.

It only has an 8 hour half life so it has minimal build-up in the blood unless you are taking it more than three times a day. For example, if you took 300 mgs every 8 hours, after six doses, you would finally maintain a blood level of 300 mgs minimum.
