Cravings!

When the heck do cravings start? When I found out I was pregnant I immediately stopped taking Adderall cold turkey (have been on it for 7 years for ADHD management) and in the past when I haven't had Adderall available, I notice I am way hungrier than usual. But lately, as of like 7 weeks...all. I want. Is bacon. Sausage. Cheeseburgers. I force myself to have this in moderation of course but it got me thinking...is this quitting Adderall cold turkey or is this pregnancy cravings?!
