Welcome to the forum Nanakaki. I also have hep C and can really relate to the fatigue. I sleep about 12 hours at a time and am still exhausted. I was diagnosed in '93 and tried the interferon, but it made my white cells drop dangerously low. I have since been waiting for a treatment without interferon, but there isn't one at this time. I went through treatment and surgery for liver cancer, and have been cancer free for 2 years. As you may know, liver cancer is a possible consequence of hep C. I had other problems, too, which resulted in 7 major surgeries within 5 yrs.
You will find a lot of information here, as well as support. It's a hard battle, for sure.
Hugs,
Connie
