Good afternoon I had the same effect with the gabapentin sleepy, feeling drugged I was taking 300mg am and 300mg at night. I asked my doctor last week if I could try and get of the gabapentin and so far it has been two days and finally getting my head clear. My goal is to go back to work and feeling foggy all day is not going to work out for me in customer service and cash handling. I just had my second ganglion block and so far the pain and heat had calmed down. I broke my arm 12/9/13 and have been out of work since. My fingers and hand are still swollen and do not bend
