I started vaping a few months ago and never really had too many issues. I was originally vaping 50/50 and 60/40 PG/VG blends. I recently got some max VG and I've got a sub ohm build. I've been getting a heavy lung feeling and seems like e liquid is sticking to the back of my throat causing me to clear my throat constantly. I never had the issue with the 50/50 and 60/40. Is that a pretty common side affect of max VG or is it just me?
