I had a nasty cold a couple of weeks ago. I should have stayed home a couple of days, but didn’t. I started feeling “off” on a Monday, started on Zicam that night. Felt a little more “off” Tuesday, then felt like crap on Wednesday-Friday afternoon. Then, suddenly, I felt better! It was weird. The most compact cold I’ve ever had. It was perfect timing, though. I think the Zicam helped. I had taken it for colds before, but THIS time, I got some free to try from BzzAgent. It arrived in the mail the Monday that I felt “off”, so I didn’t even have to go shopping! I recommend it, even though I don’t like the taste. 😳
