I did my first 48 fast and broke it last night. I felt pretty awesome all day, especially after I hit 36. I also hit 239lbs yesterday morning which was the first time I have broke 240lbs since I was on active duty, so that was cool. I'll probably transition to a 16/8 routine again until I decide on doing another 48+ fast, maybe I start it after the Super Bowl and shoot for a 60-72 or so.
