I’m trying to switch to vaping oil. I’ve started using the UNI Pro 2.0. I can’t stop these extended coughing fits. I have it at the lowest voltage. I pre-heat. I take a very short hit. But more often than not, I ended up coughing for 15 minutes.

Was really looking forward to transitioning to vaping but have been extremely disappointed. Is there anything that cane be done about this or should I just back to combustion?
