Did you have 2-3 glasses of wine every night, at about the same time? If so, your body might have gotten into the routine of having alcohol at a certain time every day. Alcohol is not very CHEMICALLY addictive if compared to, for example, caffeine, nicotine, heroin, cocaine, etc., but it isn't impossible to get physically addicted (most alcohol dependency issues are stated to be emotional/mental/psychological).

I do drink somewhat often (4 days a week or so), but rarely more than 3 drinks (almost always beer or wine) and usually just one. I am, however, hopelessly addicted to caffeine. If I don't have a big dosage of coffee by about 9:30 AM, i get splitting headaches. I need another dosage between 3-5 PM. I really would like to kick this habit, but the health dangers aren't as pressing as, say, cigarettes (or harder drugs, obviously).

As an aside, it's interesting that caffeine addiction is one of the very few chemical addictions that is perfectly culturally acceptable. I guess it's because it is very difficult for a body to OD on caffeine (the body gets uncomfortable - "jittery" - if it's had too much), and people function fine (sometimes better - caffeine DOES increase mental processing powers, however briefly) - while on it.
