Dizziness can be from not having enough of the p1 carbs-- LOTS of veggies, including a couple of servings of beans/legumes (which are more carb dense than most p1 veggies), and then also your 2 daily cups of milk/yogurt.
Your other post mentioned a lack of appetite, which I originally attributed to the fasting, but that can also be caused by not getting enough carbs. This can all be from something called ketosis, which low carb dieters love, but on SB we try to avoid. It can also cause bad breath, dehydration, and/or a weird or metallic taste in the mouth.
-- food lists, portion guidelines, etc.
