However, in my case, the sides were minimal-some aches, flu symptoms and I felt more out of shape. You don't say whether you are using Pegasys
or Pegintron. The consensus seems to be that Pegasys is easier on the initial sides, but that they are both effective on creating the longer term ones.
When I told my PA that I didn't have any sides, he said that a number of people didn't, but that they had to warn you about the serious ones anyway.
