I am on my 4th wk of 12 weeks of treatment Sovaldi/Riba and mostly the side effects for me are fatigue, flu like symptoms, Insomnia, loss of appetite, and a little nausea. Now that I am finishing up my 4th wk, I am feeling much better, it is good that your son is at home with you for moral support. My sister has been my support through the last month, it was nice to have someone do my laundry etc. when I was feeling too tired.
Overall, everyone reacts different, but my side effects were manageable and it gets better.
Good Luck to your son and you!
Hang in there!
