I use Jimmy Joy as a substitute for breakfast. I live a sporty life and climb a lot and this drink just gives me the power for the whole morning until lunch :D I like that it doesn't have overdosed vitamins but all at a normal level. I give 4 stars cause I ordered the shake with the following tastes: chocolate, wild berries and passion fruit. While chocolate is perfect for me, wild berries and passion fruit is just an agony to drink and I almost don't get it down. I was expecting a more sour taste in those two and not such a sweet strange taste they have for my taste buts. So I will just stick with the chocolate taste for now.
