I am a 53 year old female . I consume a glass (or two) of red wine most evenings. For the past two mornings I have woken up with hangover types symptoms without consuming more than normal amounts of wine (for me) from the night before. Most alarming is that my vision shakes from side to side for several minutes. After rising all symptoms dissipate. I have no other health issues and am in good shape, although I have not kept up with my exercise regime ( bike riding, yoga and Pilates three to four times a week) in the past few months. Please help!
