I was sick the whole entire time with my first and the first 4 months with this one and now I am sick about every other week =)
I handled it by being moody and overall irritated but still happy that at least the baby was doing well =)
Seriously though, I tried everything and nothing worked. The positive aspect of it was I only gained 20 lbs so I didn't have to loose much afterwards. Just know you are not the only one!
