Why don't you look into kratom tea like I mentioned? In New York I go all the time to these "CBD Kratom" stores and they sell a good green tea flavoured kratom tea. It has about 12 grams per bottle and apart from a bit of a sour taste, you can almost enjoy drinking. You too can do the same by filtering out the powder with an Aeropress and then try adding something tastier to the resulting liquid. Don't knock it until you try it!
