Why are you taking the gabapentin?

After detox, many people stay on gabapentin for quite a while to help them with the after effects. Usually the dose for detox is 600mg 3 times a day so you are ahead of the game already. Please check with your doctor about how fast he/she wants you off of the drug, but in the meanwhile you can eliminate the mid-day dose with no side effects.
