LOL...I'm not even sure one drink could count as a cheat. Take it easy on yourself!
Last year on July 4th . I made up my mind beforehand that I was going to cheat. 6 beers, 2 hot dogs, a hamburger...and to top it all off...a giant dessert plate of something at a popular local restaurant to go along with more alcohol. I'm fuzzy on what it was exactly as a result of the alcohol, but I am certain that it was delicious. And don't worry, Grok wasn't driving.
The problem with this cheat was that it spilled over into the next few days. After you wake up from a day like that, you start thinking about how good McDonalds breakfast food is, with those little hashed browns and the McGriddles...my God the McGriddles sandwich. Ketchup briefly became a part of my life again. And soon...tighter fitting pants.
My advice is that cheats shouldn't be planned, sort of like drunkenness shouldn't be planned. When this happens, overdoing it practically becomes an inevitability.
