Some what new to vaping. Picked it up 2 years ago to stop the smoking habit. Went 37 days with out a cigarette and then had a set back. I have been trying to get back on the vaping for about the last two weeks. I am struggling to find the correct nicotine level and pg/vg ratio. I suffer from anxiety, but have been somewhat controlled with meds. I seem to really be having a lot of shortness of breath after a short vape session, that I never experienced when I got started 2 years ago. Any ideas or help that anyone could offer would be greatly appreciated.
