I medicate for nausea. I think we're actually luckier than the people who medicate for pain. Most any strain, even small amounts, works fine for nausea, even buds we would all consider too shwaggy to smoke. I listen to the budtenders, but my decisions are made based on appearance under magnification. I always choose the buds with the best trichs/trim, rather than on the sat/ind balance. Ailment-specific marketing of strains is just a marketing tool, IMO.
