Just curious if this is "normal"... I have been working 7p-7a for about a year, for the last 6 months I have picked up an extra OT shift during the day. So I usually work 3 night shifts per week and one day shift per week. Over the last 4-6 weeks I have been sleeping way more than normal. I'm so tired I don't feel like working out or even getting up to eat. Usually in between shifts if I have days/nights off I will sleep for 17 hours!! I have a appointment with the doctor next week just to check but I was curious, anyone sympathize or have a similar situation?
