Are you able to do extra flavor? I bought a huge bottle of cheesecake (love it) but the only time I can taste it is first thing in the morning. Once I have coffee and eat I can no longer taste it the rest of the day. On the other hand, cafe mocha is a definate reorder, plenty of coffee flavor there. I prefer strong juices but love the taste of vanillas, cookies and cakes and usually those are light. I could care less about vapor, so do I need to order a high pg? Don't know how that all works.
