Woke up ate French toast, but didn't finish it . Afterwards I watched TV for a bit, then went back to sleep. Woke up at noon and showered. Started throwing up non stop, but it was all liquids. Started cleaning and started having hot flashes. Now I just feel weak and I don't even want to eat.What could it be? ughh feel pretty sick!!
