So I just got some new juice, 50/50, and LOVE the flavor (mmm, mmmm Rootbeer float) of the first one I've tried.  The last all PG juice I was using had a pretty hard throat hit and gave me a slight headache; this juice doesn't have enough throat hit, but, no headache (smiling).  What can I do to increase the TH?  Anything easy?  I would mix the old juice, but it's cappucino flavored....
