Hi! So, I want to experiment with different juices as far as nic levels and PG/VG combos. And flavors too! Unfortunately I'm dealing with increased tinnitus (ringing in the ears) since starting to vape about 2 weeks ago. Sure feels good to be off analogs though. Not sure exactly WHAT is causing this...figure I'd try different things. I'm looking for recommendations for places to buy e-juices online at low cost. Of course, the store would have to offer great range options in nic and PG/VG percentages. Suggestions?
