Natrushka,

Just wanted to thank you for the link.
When I was on Atkins and actively losing weight and working out a lot, I noticed that if I go for so many days without a break and have a few days of less sleep, I will get a cold every time, no matter what.

I did not know why it happened, but this explained it and I have learned to take a break and also try to not undersleep too many days in a row.
I am trying CAD/CALP now, but I do still take intrest in Atkins and other low carb and exercise subjects.
Thanks.
