I'm sure some vets can be of great assistance to you. Regarding the liver flush, check the posts made as recently as today. The common tone is "listen to your body" (I need a virtual stamp for that line *s*).
Regarding the dizziness, how many lemonades are you doing per day? Today? How much syrup? Water? Are you normally hypoglycemic at any level? I am and have to watch both my Sugar cravings and Sugar lows. It's a fine balance sometimes. This may or may not be part of your dizziness, but surely sticking closely to the regimen listed in the book can help to alleviate your dizziness (correct nutrition and hydration).
