Hey vivictus, glad to hear you're kind of figuring out what the problem may be. I never had much luck with Boge cartos, either.
You may want to consider going to 100% VG. It's hard to distinguish between an allergy and a sensitivity at the onset of symptoms (and they are slightly different things), but if it's an allergy, it can become cumulatively worse over time. So just in case, going all-VG certainly couldn't hurt.
Go with stronger flavors to get back the throat hit, if you find it lacking in all-VG juice.
