Yes it will grow back. I completed treatments 2 months ago, and my hair is just starting to grow back. Irnically I am still loosing hair as well. I have almost lost all my hair, and it is painful. I wear a hat. I know how you feel about the ###3 waking up to spit. There is hope. It will stop in time. It stopped for me about a month after I stopped treament. I still can not eat very much, and it is very hard to bear. It is worth stayig alive and I know it is very hard. Be positive. Christmas was hard for me as well. It helped me to make sure my kids had a good christmas.
