I mix with water, preferably cold water, and have it for morning and afternoon tea generally, but I keep it flexible. I might have something small to eat for breakfast (probably a small naughty sweet that the wife has made for the kids), and yoghurt for lunch. I probably still eat too much and the wrong things at dinner, as the wife controls the evening meals, but I should probably take more control over my portions. I am quite hungry at dinner time, because I'm also exercising and often have come straight for the gym. I allow myself a row of chocolate too.
I still drink a decent amount of beer, but only weekends, where I was drinking most nights before. I'm not even strict on the man shakes on the weekends, in fact, I've had some early morning wake ups by my bowels, so I don't think it has been mixing too well with the beer, so I will probably drop the shakes altogether on the weekend / drinking days.
As long as the scales keep moving in the right direction, then I won't change much, and I'm still building up with the running, so there will be more calories burned. If things plateau, then I will have to look at changing something else.
