My son has been experiencing headaches on waking which seem to disorientate him for most of the day. He says he seems to lose his memory and sensations are different. It usually lasts two days . He had a TBI many years ago and in the early days did have seizures most often related to alcohol. These incidents don't seem to relate to anything and as he takes Tegretol it seems odd that he may be having some kind of seizure. He 's not happy about going to the GP because he doesn't want to jeopardise his driving license. It only happens at night and it's fairly infrequent . Does anyone else experience anything like this?
