The fact that you think you need it to have a rewarding summer makes me think you still have a bit of a problem with it.
For most of us who drank on a daily basis for several years, we're never able to successfully moderate it. 'Weekends only' becomes 'weekends and holidays' then 'weekends, holidays and really bad days', etc. Plus, you'll just feel WORSE on Monday after drinking and spend the WHOLE week having to wait for the weekend so you can not feel like it's a dull and unrewarding day.
I would suggest finding other things you like doing to make the summer interesting.
Really, how interesting is drinking every weekend?? Isn't that OLD after doing it for more than 20 years. Get out. Try something new.
