I tried the protein shake with just water. It's nowhere near as nice as milk (which I actually quite like) but it's not awful either. I can drink it. And I don't really need the extra calories in the milk.

Made a gym friend this morning. Well, some guy spoke to me after we were both finished around the same time and gave me some advice on my squat form (my feet were pointing out to the sides). He seemed nice enough and wasn't being a patronising dick or anything.
