Need suggestions
Everyone is different but I have always used the big ol' purple bag of EAS from Sam's Club or Costco. As far as price, it's about the most cost effective you can find and it comes in Chocolate (which is what I use) and Vanilla (I am not a fan but my friends swear by this). Mostly I have BLEND with water and ice and occasionally I throw sugar-free syrup flavors in there to mix it up a bit! Good luck. I've recently had to jump back on the shake wagon to maintain a bit while being preggo!!
Love, Riah
