difficult child and I suffer from daily/severe headaches. Recently referred to a Headache specialist at a hospital about 30 miles away. They told him that daily advil will cause kidney failure (they said this to an EXTREME anxiety sufferer) Now he won't touch Advil. But continues to suffer from the headaches. We were there a few days ago and they gave him Gabepentin. Said it plays nice with Lamictal and often compliments it. difficult child has worked very hard to lose weight and is doing really well. Reading the Gabepentin it says weight gain. Anyone experience that? difficult child doesn't want any more medicine. He does take his daily medications with no problem.
