nothing formal, but yeah, i "put pictures in my head" of future events and situations and what i would be doing as a sober person in those situations.
as basic as picturing myself with a lovely mug of hot herbal tea on an evening in winter when i'm 75
yes it helped. it replaced the imaginings of sitting in a rocking chair with a glass of wine or a bottle of beer...i had those pictures in my head though the reality never was "a" bottle or "a" glass.
