2nd day of very low sugar fruits

It's be OK up to this point. Yesterday was decent, till night time. Around an hour or 2 before bed, I got very lightheaded and just lethargic feeling. My whole body, expecially head feels like dead limp weight. I also get anxious. I had a tiny bit of almond butter, perhaps that was it? I don't know. Today I woke up, had 2 scrambled eggs with a tiny bit of SCD yogurt. Been feeling good for the most part. Then after lunch I started going down hill. I had a few red peppers with some grass fed beef for lunch. I then had another bite of almond butter. Havent had anything for about 2 hours and still feel very lethargic, miserable, and feel like dead weight. Time, time, time - hopefully!
