Hot chocolate is a universal cure. I've had good luck with the following, though you might only want one of the flavors at a time:
1/4 cup Nido milk powder (any Indian store)
2TBSP Valrhona cocoa powder -- it is strong, so YMMV
1TBSP sugar (I like coconut sugar)
1TBSP Yaucono Selecto instant coffee from Puerto Rico
1TBSP coconut cream powder (any Asian store)
Put in a plastic peanut butter jar and shake to knock out clumps.
Add ~1 Cup cold water (hot causes clumping) and shake it smooth. Now you can heat it if you wish, but I like it cold.
