You know, I get that same hazy feeling, and it tends to stick with me for quite a while after I've smoked it. I really don't like it. But VG leaves this thickness in my throat like I just ran too far. I would still prefer VG because I think PG leaves a film at the back of my throat that makes my voice sound funny, and I also get this dry cracking sound sometimes if I don't drink enough water. Never used to be that way, though different problems with reg cigs were apparent. Anyway I would use VG but as I've read and researched a bit it does seem dangerous. I'm upset that they use it with the PG stuff too.
I just want my nicy-stick fix and still be able to sing =( It's too stressful having no job or car and being stuck living with otherpeople, and dangit ecigs just look so cool don't they
