Since I'm new, I cannot reply to some of the original posts concerning ethyl maltol. My husband and I have been DIY vapors for about one month. We LOVED it. On Sat. my husband had an "out of the blue" seizure that required an ambulance trip from the campground, 5 hours of recovery from low potassium and high sugars. We are awaiting test results for possible new onset diebetes since they think it may be diebetic ketoacidosis...or any other problem that would have caused his symtoms. The pre-symptoms fit the nicotine poisoning stuff that I read- but he had been about 8 hours without vaping just before the seizure epsiode. Anyone else have problems related to ethyl maltol that effected sugar levels? No diebetes or family history prior tp this episode. Thanks,Sheri
