thank you! as soon as i asked the question i found that chapter. my bad, but it's always good to get reassurance from you lovely people.
day 4 was really difficult for me? i was so nauseous and dizzy and weak. but i woke up this morning and i feel normal, so hopefully that's over. and that need for food is dying down significantly. all good things, i feel great even when i'm feeling bad.
thank you all again for your speedy help and advice!
