My partner just started rotating shifts in his lab and has 2 weeks of 10pm to 6am (then 2 weeks of 2pm to 10pm, then 2 weeks of 6am to 2pm, then back to the start). I find it really difficult, also (this is the first week of nights). I don't really have any advice but will be watching this thread because I find myself getting really panicky when he has to leave and can't seem to sleep properly either. Just wanted to give you a big and let you know that I know how you feel!!

Here is hoping things get easier for the both of us...
