I suspect that this just isn't in the cards given that kind of situation. You're ultimately just better off suffering through that withdrawal (especially since you've said you were in a frickin' hospital to begin with. It's not like you're losing that much effectiveness and productivity) and trying to find a new normal after the worst symptoms are over. It might take some time but our best guess is that kind of habituation is not permanent, so you should see quite a bit of improvement over time if you just stick to it.
I used to vape and I had the worst time quitting nicotine. I tapered down to around 25% of my usual daily intake over the period of about 3 months before I decided to quit for good. Even then, for about 3 weeks I felt incredibly tired all the time, yet I couldn't sleep, and I felt borderline mentally retarded... it was really bad. It took me about 3 months to feel more or less normal again, and cravings completely went away when I was properly diagnosed with ADHD and started medication about a year later.
