The package insert which comes with the IFN states that depression can be an issue up to six months post-tx.
We had another thread about this just a few weeks ago. That was from a person whose depression actually got worse post treatment. It takes a few months for the drugs to work their way out of your system and during that time it appears that you can have a number of symptoms both old and new. It seems like the only solution is to be patient.
Good luck. Praying for SVR.
Yes, it takes a while to get back to normal after TX. In fact, some people here who have recently finished treatment have found their depression to be worse for a while right after treatment is over. That doesn't hold true for everyone, but it does happen.
I'm sure those with more information will be able to give you more information on this.
For now...I'm very happy for you that you are POST treatment!!
