First post was 3 hours ago ....I'm so tired , I felt fine 30 minutes ago and so I went back to sleep , as I am falling asleep it happens again , my stomach does sort of a spasm..and then I get cold , shake and here I am again on the computer trying to get my mind to calm down . I 'm not bad but I feel nausea and I want to sleep , I can't ..How long will this last for ....it has never happened like this ..I almost want to go to the hospital so they can give me something to sleep....anyone has any tips on what to do now ...
