On May 4, I was on a boat in the ocean and got seasickness. I vomited for 3 hours. When I got back to dry land I felt better but the next day I started to have diarrhea for 5 days. Then I was fatigued, mentally foggy, weak, and had aching muscles for about a month. Then it went away. Last week, I started having the same symptoms again and just want to sleep a lot, feel like I am walking in a fog. Any advice?
