My Husband has no fever, but has not got out of bed all day. 63 yr old male, bit overweight, at 3am last night he ate a whole strawberry cream pie and 8 breakfast bars right before bed. 5'11" 250 lbs he has vomited anything he put in his tummy today, be it water, juice, anything. Heaving vomiting. Still in bed at 9:30 pm. Is this dangerous??
