I am feeling HORRIBLE! I can't taste anything normally either. My mind is mush, I cant go to the bathroom without breathing like I ran a marathon, I lost 20 pds in less than 2 weeks ( which puts me at 110). I slur, I have cotton mouth, can't sleep, I stare into space endlesly, my stomach and back ache, my mouth aches and I feel so tired. Everyone says I am acting abnormally. I am misirable and so is my husband, I am scared and feel so alone. To top it off, I still have a headache......
