I know we've got some smart cookies on this board (uh oh, this diet is gonna be harder than I thought if I'm already thinking about cookies) and some health care professionals and I need some help. I'm trying to find as much stuff in the store here but they don't have everything I need. Here goes: I need Threelac and I know I've heard people talk about this. I can't find it here. Anyone got a cheap source? I also need eleotin tea. So far, I've found this stuff is pricey - a source anyone? What should I look for in a shower water filter? Again, price is important.
