I got a weird flavor when I used isopropyl alcohol, so now I boil my attys. Boil water, let them sit in it for a few minutes, air dry a bit, dry burn and everything is okay. I switched to rebuildables recently, so now I don't have to clean my coils, but still boil to clean and sterilize my RBA's.
I know the feeling on cutting back though. I go through phases where I vape heavily, then cut back a bit. I notice flavors start to taste the same, and I don't crave as much. Usually a week later I get stressed out at the world and need a way to calm down, so I vape heavily, slowly weening off until I don't vape anymore. I would like to switch to 0mg, or at least have some around because it isn't the flavor or feeling I dislike, it's the need not to have nicotine all the time. Try taking a week off, let your new juice steep a bit. Boil your attys, and then come back and vape again. If you still dislike it, then quit if you feel so. But, sometimes, a little bit of time is needed.
