I don't drink because I have yet to find an alcoholic drink that tastes better than a cup of tea!
On the odd occasion when I have had a glass of wine at a social occasion I always develop a headache.
I know how easy it is to become dependent, though. A friend had difficulty with getting to sleep, after her husband died. She found that having a drink before bed helped with the problem. Unfortunately she found, after a while, that she needed two, then something stronger, and didn't realise that she was getting hooked on drink.
It was only when her family and friends became aware of how it was affecting her that she realised that she had a problem. Luckily it was a wake-up moment for her, and she managed to stop. She doesn't drink at all now.
