Pregnancy cravings getting the best of me, how about you???

I am 3 months pregnant and all I eat is mexican food, I eat nachos, salsa, taco bell, taquitos, and anything mexican but prior to getting pregnant I didnt care for mexican food. My very first craving before I even knew I was pregnant was doritos. One night at 3am I awoke and asked my husband to go and get me some doritos, he yelled at me and told me to lay back down, I cried for those doritos.... I shouldve known right then and there I was pregnant but I didnt find out until 2 weeks later. My husband brings home cheese and tortilla chips every day after work because he knows I ate it all while he was at work, and usually I did. My cravings are getting the very best of me, I wont eat anything else, is this healthy for my baby and what did you girls crave during your pregnancy. I would love to hear about your cravings and if they are getting the best of you as well??
