Only want chocolate.

So I haven't experienced any morning sickness but food will nauseate me. I have only been able to get down chocolate, apples, grapes, halo's, tuna with lime and Mrs dash (only once a week), goldfish, rice, and mashed potatoes. That is literally the extent of my diet. And today I took one bite of a halo and spit it out instantly so scratch that off the list. This baby is going to starve me. Should I buy like meal shakes or something? I haven't eaten an actual meal in weeks.
