When I try to start the keto diet, after 4 days I crave simple carbs. As a recovered alcoholic and addict with many years of sobriety, I find the feelings to be exactly like the obsession and compulsion I experienced as an active addict. Although I have no compulsion to use substances, I find the compulsion to use to use simple carbs the same. A feeling I find disturbing and don't understand. Can you advise?
