I drank quite a lot at uni but for years now I rarely drink maybe 3 glasses of wine a month max. It really doesn't suit me at all to stay and feel healthy and I just don't feel any desire to drink or feel drunk anymore. The longer you do it the less you want to go back to old ways I think. My skin is probably better now than it was in my 20s we definitely can speed up ageing big time with bad lifestyle.
