Yeah. Schedule transitions are never fun. Good luck on the new job man. You're gonna kick ass.
I used to work one night shift a week and my boss would book my next day shift the day after I finished my night shift. So I worked Monday 7am, Tuesday 7am , Wednesday overnight and then Friday at 7 am. She somehow figured Thursday was a day off even though I was definitely working on it. I had a sort of routine where I would push myself to stay up late Tuesday so I at least slept in Wednesday and then on Thursday I would only sleep about 3 hours so that I could get to sleep at night for my Friday shift. The only worthwhile thing is we had this piano in the store and this man would come in almost every Wednesday night to play Mad World. He played other things, but that one was my favorite. Point being, schedule transitions totally suck.
