Dont stress to much. I had a bad night as well last night. Had a friend come over for a catch up "coffee and chocolate". I had bought some chocolate and she also turned up with 2 blocks! (we only ended up have a little, so now i have 4 blocks of chocolate in the fridge). When she got here, we ended up going to the pub over the road for dinner and i had chicken schnitzal
Just start again the next day, its not the end of the world. I made sure i made the effort to go to the gym this afternoon.
