Does gabapentin take a long time to take off my headhake problems?

Neurontin (gabapentin) headache. Depends on what are the other health problems that cause the headache. Again = treat the overall cause and not the symptom. Gabap is not the first line med to treat headache. If it is well chosen, as i suppose it has been, the benefit may occur rapidly. The dose can be doubled every 3-5 days till benefit is achieved. Good luck.
???? This best answered by the doctor who prescribed it for you, Gabapentin has a very wide range of daily dosage and it has multiple indications for different types of headaches, it usually works within several days but it all depends on the specifics, so please check with your prescribing physician.
