Hello, I never let myself take naps because of how terrible I feel after it, I feel so awful if I felt it at any other time I would be worried something is seriously wrong. I just unintentionally fell asleep and was woken by my dad coming home from work and felt horrendous after, feel completely out of it, so sick and dizzy, plus I sometimes get a pain in my stomach which may be because of stress or stomach problems and that is hurting. I was wondering two things, one, why does this happen? And secondly I have realised for quite some time that when I feel at my complete worst it is when I wake up in the middle of the night feeling so sick it is ridiculous, and was wondering if the feeling is being caused by the sensation I get after having a nap, although I do wake up every night pretty much without fail and when it is linked to being awful my stomach has normally had some discomfort the day or two leading up to it and it is quite rare when I feel really awful, maybe every few weeks? But I still don't feel great when I just wkae up at night. Any ideas? Thank you Ps. My nap was about 20 mins which I thought was a good amount time for a nap.
