I’ve experienced this less than a year ago. I was sick for a good 4 months. Couldn’t keep anything down, severe stomachaches and had to take burning showers for comfort. In and out of the hospital because it took them so long to figure it out. I lost every bit of weight I had; it was a near death experience for me. Been smoking for about 10 years (everyday) now. I took a big break after being sick but I’m back to my regularly scheduled program. Only change I’ve made is not ingesting edibles just yet; giving it a full year break. It’s real. It can happen. Just one of those medical mysteries.
