Hi Hopeful, welcome to the forum and congratulations on finally getting treated after 22 years
You must be extremely excited. Sorry to hear you're having some side effects, the good news is that they usually last for the first week to 10 days only, and they are usually reduced to a large degree by drinking plenty of water, that's the most important thing to do right now.
Here are a few more recommendations to follow during treatment :
1. Take your medication at the same time every day just before or with food, as it helps with the medication absorption.
2. Try to get enough rest and eat healthy (plenty of fruits and vegetables).
3. Be careful not to take any medications that may interact with your Hep C medications. This webpage will tell you about any possible medication interactions

Additionally, the 'During Treatment' section of the FAQs page fixhepc.com/frequently-asked-questions.html has some more detailed information.
Hang in there Hopeful, the side effects should subside soon, especially if you drink a lot of water as I mentioned, it will all be more than worth it at the end.
