Milk needs to be curdled in your stomach in order to be digested. Children produce an enzyme called rennin (also called chymosin) for the purpose. It used to be extracted from calf stomachs for cheesemaking. After you stop drinking milk for some time -- I'm not sure how long it takes -- your stomach ceases production of rennin. If you try drinking more than a small amount of milk when your stomach doesn't produce rennin it makes you feel queasy... a little like having too much oil in your food. A small amount is able to be curdled by the acid in your stomach I think, but without rennin most passes through to the small intestine without being digested. I never stopped drinking milk so it works fine for me.

The cats are preventing you sleeping in your new bed! It is a conspiracy. :)

Most comfortable bed I ever had was a piece of foam about 2 inches thick on the floor. It was amazing.
