If you enjoy your skim caramel latte, and you're not having much more caffeine than that, I'd keep having it.
As for alcohol, I love to cook with wine, and continued doing so when I was pregnant with all of my babies... the alcohol gets cooked out of it anyway when it is over heat... as for desserts, I don't really eat alcohol in desserts, but I guess a little can't hurt you.
Enjoy!
