Haven't read most of the posts here; but after my last 4 month diet (severe caloric restriction and lots of cardio, 0 cheat days or refeeds) I went on a massive binge that lasted a bit. After 2-3 days of binging I was holding OVER 12lbs of water. My hands, legs, and ANKLES were ALL swollen.
I went to the hospital to get checked out because I was thinking it's probably kidney issues (was running dnp at 250/day) or heart failure. Got all checked, and all looked perfect.
They cleared me out with no explanation other than your body's just in shock. I dropped the GH and went low carb for 1 week. Dropped all the water.
