I've been a fairly heavy drinker for years - drinking until drunk twice a week for about 20. On Thursday, I drank to the point of passing out at home. Woke up with standard issue hangover. Crazy anxiety. Heart 90-100 beats per minute. Sweats... I'm better now. Blood pressure is fine. Pulse is normal. However, I am having muscle spasms in my legs. They don't hurt. They're like annoying waves -- restless. Is this due to vitamin deficiencies? Lack of sleep? Anxiety? Thanks.
