Itchy breasts, smell changes, throwing up after eating big meal and drink?

I came out of the bath around 6pm, its 8:21 pm now. I'm wondering After I eat alot and drink only one cup when I burp I'd throw up a bit and spit it up in the sink... also My sense of taste doesn't like caramel candies. Also now I have itchy breasts. And yesterday I was sleeping and felt a fluttering in my stomach underneath my bellybutton. Also The itching is getting worse.... =O The itch is on the inside of my breast... Help would be wonderful. I also sometimes smell stuff that others can't

 

Two days ago I was lying on my bed and smelled mushrooms on my cushion, three days ago I smelled honey in the air...Also sometimes I smell kadaver in the bathroom and also hamster...
