There is something nasty going around here in the states. 3-4 weeks ago I had a bad cold, shook it but during that time I wasn't 100%. A week and half ago I developed what I thought was something that had to do with my contact lenses, pain in both eyes, watery, some discharge and extreme sensitivity to sunlight. Wore my glasses for a few days but still had the watery eyes and couldn't see clearly. It passed then a couple of day ago it came back twice as hard. Went the doctors...severe sinus infection. Stayed in for a couple of days working from home I did go to the school for field work with my kids...bad idea and almost passed out. At the gym now, did a little vacuuming and almost passed out again. If he knew he was sick I seriously doubt he was restricting fluids much. It could very well be a virus.
