Has anyone ever done a meal replacement shake?

I am trying to eat better but its so hard!!

I am doing great at exercising a minimum of 5 times a week - for the past 2 weeks anyways - plan on keeping this up!

Anyway - I was looking into Shakeology and came across IdealShake - its cheaper and lots of reviews say its tastes better than Shakeology.

I was thinking about doing it for 2 weeks (2 shakes a day and then 2 snacks and a healthy dinner) to see if I can kick start a weight loss.
