I put the acacia in first and then add the tea. I find this makes it easier to mix. When I was working I put these in a little Rubbermaid condtainer with a flip top that I could drink out of. Acacia never thickens so no worries with that. YOu just have to shake it really good to mix.
I think you will find that it is easy. I don't like to drink it in plain water because it has a taste that I don't like. It really is almost taste free but there is something that bothers me about the non-taste in water. If that makes sense.
