Nice work! Good luck on the cooking/food class thing. Western culture is constantly bombarded with food so the challenges are ongoing. You'll do great! Be careful getting up from sitting and lying, orthostatic hypotension is common but you don't want to fall. It also means the fast is working already, your blood pressure is dropping. :) When I fast, I have to stand next to the bed for a few moments after getting up before I can start walking, just to get my equilibrium.
If you feel as if you will fall or faint, DO NOT look for a place to sit or lie down - lie down where you are and don't try to walk anywhere.
Good luck, keep us posted!
