im on the 4 shift pattern. its basically 3 days 6am-6pm, 3 days off then 3 nights 6pm-6am and so on nights arnt really that bad if you get in a pattern. if you work the shifts i do you never really get in a pattern cause your constantly changing from days to nights the best thing i can say is keep drinking coffee or an energy drink or 2 and get to bed as soon as you get in. thats what i do.....oh and nights do temd to go slower than days I've found but its good at night ause you can chill a bit and all the big bosses arnt there to bother you just your team leader/supervisor lol so you can chill out a bit
