If you're not sure about the meds combo Bella, the best thing to do is speak to someone who can advise you accordingly. Whilst a pharmacist will be able to provide general advice about whether meds are OK to take together, your GP is the best one to say if this this particular combo is suitable for you.
The Gabapentin need time to get into your system, this can be anything from 1 to 3~4 months, so you are unlikely to feel any immediate benefit from them. The dosage tends to be increased gradually as well, to a level suitable for you.
