So today I loaded up my vape thing with 12mg juice (I have 12, 6 and 3mg) and left the WC at home, just vaped that all day. I'm not even an all day vaper, a puff or two here and there. OMG, I feel like a different person physically. I have heart disease and I felt great, no shortness of breath, not a lot of tiredness, just felt better than I have in a while. I don't know if it was the switch from 24mg to 12 but I hope it keeps up!
