Another drink to try if you already haven't is the Vanilla Nut Milk. Going from memory (it is in cookbook for anyone who wants to look it up...)1 cup skim milk, 1 tsp vanilla, 1/4 tsp almond extract, and a packet of arteficial sweetener. Counts as a dairy.
Recipe calls to warm the milk...but I am not a hot drink fan (can't do coffee, tea, hot chocolate unless it is the iced version or I let them go cold...) so I just mix it all up and drink it without warming.
I decided to try this to get a dairy when I get bored of yogurt. Made the transition from whole milk to skim milk easier - tastes sweet and feels like I am having a treat
