I went through the most major changes in my life (next to having children) in the first year of my sobriety. I left my husband, moved to a different state, then went through a divorce.
I think those changes were neccesary in order to make positive changes in my life.
YOU are the only one who knows deep inside what is right for you. I think the suggestion not to make major changes in the first year is just that, a suggestion.
