Welcome!
I'm new-ish here, too. I started IP 2 weeks ago and I'm already down 11 lbs.
I was also scared of the headaches since I get migraines often. I started on a Friday so that I had the first few days at home. I was pleasantly surprised that I didn't suffer from any headaches or dizziness that others have described. I really really think it's different for everyone.
I don't drink caffeine so I can't help you on that front.
As for the kid's snacks.. my husband is an angel and he's been making their dinners/school lunches etc. Although for dinner we mostly eat the same. Tonight the family had tacos and I had a taco salad (minus the tacos, cheese and sour cream)
It will take a couple of weeks to get used to NOT cheating.
My vice is chocolate milk and it was hard knowing we had chocolate milk in the house and I wasn't able to drink it.
Good luck on your IP journey. We're all in it together.
