Congrats on being smoke free. I am at three months and I find myself using both. I can't wake up and hit the PG. It's just too harsh for my first vape of the day. After a while VG seems a little week so I move to 60/40, by night I am hitting straight PG and loving it.
This probably didn't help much just because it really is different for everyone. It's just what works for me.
Good luck and keep trying, that's what works for most of us (as I sit with crossed fingers).
