You should be fine, but I would definitely limit the buckwheat to just one bowl a day. Have you been using Molybdenum? Because if the detox hasn’t caused die-off symptoms, the coconut oil should.
The sugar craving was just a reminder that you still have Candida to the extent of an infestation. The Candida don’t want you to forget they’re still there (unfortunately). But that’s all to be expected. You just stick solidly to that diet and their numbers will start to lessen soon, if not already.
You’re doing great.
