I have been suffering the same symptoms as you guys, I wake up 4/5 days a week with an immediate gagging feeling, and it will not go away until I have either puked (usually for 2-3 hours) or smoked pot. It started when I moved back in with my parents, about four months ago. There's some stress with me wanting to get a job to fix my car up, but it's not alot of stress, I have however, been drinking alot of caffeine. I used to drink two cups a morning, but then I got this office job, and drank coffee all day, probably about 5-6 cups a day, and I didn't know it but I became addicted to caffeine, and I would find myself slurping a large latte from the late night gas station before bed, drinking coffee from morning to night, 9am to around 3:00am... Not healthy. Then I got fired from my job and moved in with my parents again, where I would drink coffee almost the entire day, probably about 8-9 cups a day, from 9am to 3-4:00am, missed alot of sleep, played alot of video games. You get the idea. My father had a similar problem, and it turns out it was his tooth roots growing too deep, the roots ran into his sinuses making him gag every day for decades, until he underwent a series of root canals to remove the teeth interacting with his sinuses, that may be something you guys want to look into. I have poor teeth like my father, and I'm thinking that, or a gross over absorption of caffeine is the issue in my situation, what does your caffeine intake look like?
