Back in April I started having some stomach problems, burning in my stomach with pain, belching, nausea, ........ and a bad taste in my mouth. I saw my doctor and she ran blood tests and an ultra sound. She couldn't find anything physically wrong. She diagnosed me with acid reflux or GERD. I took meds for 2 months that would heal any lesions, if there were any. She gave me a list of things I shouldn't eat and told me to lose weight. No problem when you can't eat. I've lost 30 lbs. Here it is July and it was getting worse. I ran a search in this forum and found someone with similar problems. Someone suggested that vaping at a higher wattage was probably the problem. The higher the heat the more concentrated the nicotine became. Nicotine poisoning? It's been 3 days since I turned down the watts and all my symptoms have disappeared. I thought I would put this out there for all the others who have been suffering with stomach issues too. Maybe I just got lucky figuring it out.
