Gabapentin can be divided two to three times per day or taken all at once, with or without food. The levels start to drop in your blood stream 5-8 hours after taking it. Most people prefer to take it at night, as it can cause drowsiness, but it is fine to take in the morning if that works better for you.Gabapentin can be divided two to three times per day or taken all at once, with or without food.
