Sadly, I *do* that feeling all too often!
Th last time was at work on Thursday for lunch. Me and my friend take it in turns to bring lunch in for us to share, last Thursday was her turn, we had beef casserole, with a bread roll, and veg, followed by chocolate pudding with cream. My work pants were too tight all afternoon, I wanted a snooze and I almost physically couldn't move, I spent most of the afternoon slumped over a till, serving customers was a real effort. Never again*
*Until next Thursday anyway.
