Is it possible to develop a severe sensitivity to PG even after vaping for 4 months? I feel like a complete idiot asking this now after making such a big fuss about the MFS nicotine liquid being bad, but I didn't know this could actually happen. I just thought it was an excuse for the supposed awful nicotine. I was digging around and found an old bottle of desert ship I had made a while back and I know I tried it then and it was okay(not the flavor I was looking for), but now it too burns my throat. I poured out all of my MFS supplies as I was angry and knew it was all their fault and felt they could care less, but maybe it wasn't. I'm hard headed and dense at times which doesn't help when you know you're right when in fact are wrong. I'm going to order a small bottle of 100% VG 18mg to see if that is okay. I usually mix my tobacco mixes at 70/30 PG/VG, but I guess I may not be able to anymore. I've been on analogs the last few days and I have to say I still like them even though they stink... Anyone else ever experienced this severe PG sensitivity to develop even after vaping for a while?
