Dee says you may experience some low level discomfort when you stop drinking. I think that differs from person to person. I experienced a deep and profound discomfort which still has not disappeared completely now 7 months sober. I was prepared for that. Alcohol was also the centre piece of my life. Work and care for my mother with dementia and drink. That was it. Stopping was hard, it still is. But since I expected hard it was ok. Seeing a therapist may be the best for you now. That and just jumping in and doing the hard yards.
