My ex brother in law was a Junior Bodybuilding Champion many years ago and a few weeks before competition he would eat nothing but Tuna and only drink a lil water and a cup of black coffee and he was very grumpy until after the competition my sister said. It's just a side effect of starving yourself I reckon! At least you got something to look forward to, lol.
NEVER GIVE UP
