Gabapentin and Codeine (Co-codamol)

Is anyone else taking the above together please? I've been prescribed 300mg of gabapentin 3 times daily and also 2 X 30/500 co-codamol as required. It seems to be helping the pain the two together better than each separately so far.

I have some quite severe pain problems including neuralgia from shingles and adhesions from previous surgery.
