I always found the medicated candies to be more of a "base" for vaping, in that they don't work as well as I'd like them to, but as soon as I take a few puffs from the vaporizer, it compounds the effects. Edibles get me every single time, although they come with the commitment to actually keeping it down long enough to be absorbed (45-60 minutes in my case, and probably generally the same for everyone.) Then again, I haven't really tried looking for other candies, no doubt there's better ones out there, and worse too. Nothing like getting a "DANK-O-CLOCK 2 GRAM BROWNIE" only to see that the company fine-printed the fact that they use lower quality shake, and you paid the same/more as the ones you KNOW are good, coming from people that you have met...
Maybe a quality tincture could help as well? The last one I made a few months back, out of ABV I should add, was surprisingly good for nausea, although it didn't do much else. Just some random mixture of 3 different strains. Although even that might present a challenge, I know I've had bouts of nausea that my own saliva makes me want to puke, and sometimes even breathing itself. Hope for a speedy recovery for all of you.
