The good news is you came looking for help instead of giving up. Good girl!
Most of us added fruits and grains slowly. (Have you read this thread?
How to add new things slowly...) I couldn't wait to have hot cereal again, so that's what I did first - steel cut oats in the morning. I added 1 serving of fruit at noon a few days after that. I didn't always have both on the same day but I knew I could if I wanted to. It was probably 2 weeks before I dared to try anything else.
But that worked well. Going slow helped me know right away when something was NOT going to work for me.
As it turns out, I'm happy with one grain and one fruit most days. When I have more than that I have trouble getting enough veggies in.
Phase 1 never hurts. If you want to, then go ahead and do a few days of the familiar while you make a plan for easing into phase 2.
I would probably get right back in the saddle and start a clean phase 2 this morning. If you add only 1 grain (or fruit) a day for the next week or so, you'll be eating closer to phase 1 than a full phase 2 anyway and that should be enough to get you back on track
Either way, good luck to you. Take it slow and you'll be feeling in control again in no time.
