My boyfriend is sick, not sure what it is but last night he kept saying he was cold even when the house is 72°F and he was running a fever, then he was light-headed and dizzy and he ended up puking half the evening. Woke him up for work and our daughter woke up too, well now she's puking and running slight fever
