Need protein drink, but

 I stopped using a protein drink a while back because I couldn't find a reliable source for AchievOne.
I just found out that I have a huge need to supplement my protein, and am looking for recommendations for the best product.  I really liked the Vanilla Nut flavor of AchievOne, but while I would like to find something similar, I could probably do chocolate if I had to.  I am looking for pre-mixed, as well as something that will not destroy my taste buds.  I am also looking for a reliable source, as that was the main reason I stopped using AchievOne.  Any suggestions and/or direction is greatly appreciated.
Thank you.

Hello. I found a whey protein drink I love. You get it at Wal Mart and it is only $15.00 for a big 2 lb. can. It's called Body Fortress. It's 52grams of protein. I took it to my Dr.'s for approval and they said it was fine to use. I use one scoop for the morning and a scoop in the evening. The one I like is Cookies n Cream. It definately helps the sweet tooth and is very satisfying. I use skim milk with it instead of water. I believe it comes in Vanilla also. Hope you like it!

Have a Happy Thanksgiving.
