Starbucks Addict Question

Starbucks Addict Question

I know there was a Starbucks post a week ago but I didn't think I'd get a response to my question so I made a new post. I'm ADDICTED to Starbucks Caramel Macchiatos. Two problems : 1. They are stupid expensive 2. I'm on South Beach so no sugar. I've solved problem #2 with sugar free caramel sauce from the store but how do I make one at home? I have a stove top espresso machine that was a gift so I have the espresso part. I don't have a steamer. Do I need one? I don't really need foam. I don't think. Can I just heat milk or must it be steamed? How do you steam milk at home? My friend who works at a coffee shop ( not Starbucks) says Macchiatos are just espresso and foam. But I know that Starbucks adds milk to theirs. She claims that then they are NOT macchiatos but lattes. I'm confused. Help! Also, anyone figure out how to make a frappuccino at home? A sugar free one? TIA
