cinn is a very strong if not over powering flavor. the tiniest bit will really rip the skin off your throat. Bavarian cream as mentioned would work well. now you said your not a diy person thats cool. go find yourself a
juice that would mix well with the cinn and mix the two. or cut it with VG. vg is great you can get it at walmart, its cheap but very thick.
there are lots of ways to tone it down, hope you were not too badly hurt, cinn is rough and will even eat the rubber seals on tanks.
