How long have you worked that shift? A former SI was a sheriff's deputy that shift.. a killer, he just could not get used to sleeping those "odd" hours. He was custodial dad to 2 kids & was a mess the many years he worked those hours.
I give anyone credit who can condition their bodies accordingly.
I've worked 3rd for a Year now. It's not too bad, it's easier to work 7 days a week than to take weekends.
Doing the clock switch makes you feel like crap just in time to go back to nights. On a 3 day weekend like this it's not bad.
