Posting here for traffic. Yesterday I had a sudden feeling of sickness come from nowhere. Today I have slept on and off ALL day and feel so so sick, although not actually being sick. I have no energy whatsoever. Has anyone had this before? Could this be a bug? Even although I'm not physically being sick? Starting to feel really down now as feeling very ill with it. Now can't get comfortable as the sick feeling is worse than earlier. Aibu to call doctors tomorrow?
