I have always enjoyed red wine but recently even if I only have a glass I will wake up during the night with a crippling headache. The headache often results in me being sick - almost like a migraine. It wakes me up and leaves me feeling awful the next day. Obviously as I appear to have narrowed it down I will avoid drinking it. It doesn't seem to happen with any other alcoholic drink. Anybody else had this? I'm mid 40s if this is relevant.
