My hangovers were typically in the form of nausea- I got used to throwing up every morning before work. Pretty shitty way to start your day but I always felt close to normal after showing up. But I know for many folks, hangovers only get worse as you get older, especially women and especially while drinking wine. Seems to really start in your mid-30's and you're only about 30 right? So it seems like quitting entirely is the probably the right move.
I didn't use CBD all that long but never had any negative experiences on it- the effects mostly seemed to fit the description: was very mildly relaxing but barely noticeable even though I hadn't used any cannabis for 7 years when I started trying it. And as my tolerance grew, it became less and less effective so I switched to THC and never looked back.
Glad to hear that things are looking up in the job search and rent payment departments (still mindblown re: how badly Canada ####ed up covid relief). And that your sister's ok- Jesus that sounds scary.
