Opiates. I can barely tolerate Hydocodone it makes me nauseous. I'll take it till I can finally breath again without my back grabbing. Usually three dosages is it. Over the years I developed a strange intolerance to lettuce. A family friend underwent stomach banding due to dangerous weight issue. The doctor warned her do not eat lettuce because it contains enough opiates it would make her sick. I would bet pouring hot grease over it would make it stronger as well.
That’s interesting. I have the same problem. My sister did as well. At least I know I can never be addicted to drugs. Or lettuce. :)
