another hike today, and my water froze.. again.. I'm using a hydrapak 2l bladder in a MEC 9l backpack. There isn't enough room for a seperate bottle, even a small one, and my budget is too tight for an upgraded pack.. I bought the insulated hose but that didn't help either.. I've tried keeping the hose inside my coat today, but the other end (near the pack) froze.. there must have been some residual water left after I blew it back in the bladder.

I've read a little alcohol will do.. Is that a practical joke for new hikers, or does it work? if so, how much do I add?

Other tips are appreciated. I tend to drink quite a bit of water (when its not frozen)

Thanks for your time
