The first day I bought it I woke up with a sore throat. For the next few weeks I didn't use it much because I had trouble getting organized, no spare parts at all. I finally set up my station where I keep my kit, got an extra battery, juice and carts. Now I'm having fun again and cleaned all the ashtrays in the house, and my biggest ashtray: my car, was so gross. I love my "inhaler" (its keeps me from hyperventilating during stress at work, haha) but the only downside is a sore throat in the morning after I use it. I still smoke some analogs, but only as a backup and during transition, and I want to not buy anymore, but my voice is ugly in the morning. I'm gonna focus on drinking more water and smoking less analogs and hope the throat thing goes away, but does anybody else have advice beyond that? like coolcarts, PG vs VG, refilling, blowing out atomizer, what works for this? One of my reasons to quit would be so I could sing again, but my voice is much worse right now.
