I promptly gained weight. So that was great.
But this morning was the first time I noticed any positive change at all. Getting out of the shower, I noticed that my leg (the left one...I presume the right one matches but I didn't investigate) resembles something a little less like a gelatinous sack of oatmeal, and something slightly more like a really firmly packed sausage casing. Not yet the rippling, thrusting hunk-of-chiseled-marble that I feel is more in keeping with my lifestyle and image, but palpably less pathetic than before.
So hey. Forward progress is everything. If I keep this up, in a couple of years, I might needs some new pants!
