Suddenly feeling sick. 6PM today. Headache, weakness, whole body aches, nausea (vomiting), fatigue(slept all day), chills, low-grade fever (99.8).Barely feel pulse, faint heart beat, slow deep breathing. Felt like immune system was reacting to something around 6-7AM. Called off work, not sure what was happening. Felt OK until 12PM - vomited, then symptoms started appearing. Ate fresh salmon the night prior. Roommate had few similar symptoms earlier this week (vomiting, fatigue). Not sure what is going on.
