sick from sleep?

Ashley
I'm currently 12 weeks, is it possible to feel sick from not getting enough sleep? I work two jobs, 7am-1ish baby sitting and then 2:30-11pm I don't get home till about 11:30 and in bed by midnight then back up by 6am. I try to nap in between jobs but I'm still exhausted. Every night I have been sick to my stomach and just feel yucky then by the next morning it's just the usual morning sickness. Is it possible that I'm getting sick because I'm not getting enough sleep? Sorry this is my first!!
