I take 800mgs in the morning and 1600mgs before i go to bed and it says for sleep. she also put me on provigil to go along with the neurontin. It was my understanding that together they were going to get my neuro-transmitters firing right again. I had a bad experience with lexapro and this is supposed to be the answer. It's also to help with my pain. I don't think that it helps with my pain at all. I take different medications for pain. My other question is will the neurontin and provigil be alright to take with the oxycodone that I'm taking?
