Hi, Dee Linder, and welcome to the forum. Is the doctor who diagnosed you a hepatologist? If not, you should be referred to one. Also be sure to ask what your test results mean. It is not likely you will suddenly die if you get hot and sweaty. I don't know where your nurse friend got that bit of info! You can do whatever activities you feel up to doing.
Yes, the current treatment is a combination of 2 drugs and it's a 48-wk. course. However, there is a better treatment becoming available early next year that adds a 3rd drug and has a higher success rate, which only has to be taken for 24 wks. I am waiting for that one myself.
The only symptom most people with hep C have is fatigue. The danger is that it can lead to liver cancer (which happened in my case) and cirrhosis (which I also have.)
The most important things you can do for hep C are to abstain from alcohol intake, eat a nutritious diet (lots of fresh fruits and veggies and water) and get sufficient rest. You will also need to make a decision about treatment.
