let's discuss alcohol.

There's no denying that alcohol plays a major role in the life of most American adults. Occasional drinking has been said to improve health, but frequent binging at happy hour with co-workers doesn't.
Drinking in excess can also put you at risk for certain cancers, diabetes, and liver disease, among other grim conditions. Aside from the serious dangers of drinking too much, there are also a number of other not-so-pleasant effects, including lousy moods, crazy sugar cravings, excess calories, liver fat, poor sleep habits, and foggy concentration. Not to mention, all alcohol is dehydrating, which means dull, dry aging skin.
Bummer, isn't it? But yet, I am not saying you need to stop drinking all together, unless it really is becoming an unhealthy habit for you. My point that I am trying to make is that you can make mini rules to drink less so you can see the changes yourself slowly. Examples of these little rules would be I can drink on dates and I can drink on holiday. Be careful as it would only be a matter of time before you are back on that cycle, so you need to decide to nip it in the bud and remind yourself how epic you felt that first month of notching it down with the drinking and also remind yourself what your goals are for the year.
No harm in trying it out for the first 30 days and see for yourself the changes it really does to your body.
