I try to drink the same amount of water and get the same amount of sleep but my temperatures are all over the place!

Could it be because im coming off 3 months of hormonal birthcontrol? I figure it's because I sleep in a trailer now and and the temperature in here fluctuates like crazy, some mornings I wake up in a sweat and others I'm super cold... Does this have an effect? Is there any way I can make them more consistent?

Thanks
