I work with a guy in a secure NHS hospital who's been placed on a nicotine regime. He has nicotine spray on the hour then a lozenge the next hour and so on.
He really is a slave to this and I see him constantly clock watching and getting more agitated as the hour approaches. It doesn't help in that he can't tell the time easily so is constantly asking how many minutes are left to go.
Sometimes the nurse is a few minutes late in administrating the legally prescribed poison and that can lead to him becoming unsettled on occasion. It's mentally draining for himself, other clients and staff alike.
I believe in cold turkey myself as anything else is just prolonging the pain of something that has to be done eventually.
Good luck @BeautifulAspie1970
