In my experience, if you go 'cold turkey' from an addiction the pain and horribleness lasts longer than a few days, but does get better.
As an example, 3 months for giving up smoking, then you have a good chance of beating it.
I had a back work accident at 45yrs, then 3 failed back operations, off on workers comp., then 2 years used up my long service leave. Company pensioned me off, Mrs left with the kids and left me lying around on every medicine drs kept throwing at me: strong pain killers, antiinflamatory, heaps of valium, muscle relaxants, massages, rehab hospitals, large doses of Aspirin, medicine to stop the fire in my stomach, medicine for constapation, antidepressants etc. Plus Vodka.
I was a mumbling mess.
One day I just stopped all the tablets, everything, went to a clinical sycologist, started pushing thru the pain with walking and exercises and 3 years later, re-did my Surf Bronze medalion (just to prove I could do it).
So you can get better, but it's very painful and difficult.
I'd day just go 'cold turkey' for 3 months or 87 days (mark them on a whiteboard).
Purchase 'Headspace' a meditation app. and do the 365 day sessions.
Buy the gunga oil and have a couple of drops before bed.
People will say it's dangerous to go 'cold turkey', but it works.
