Hi Tkelly,
Yes for me it was. Something else I forgot to mention and I thought was quite bizarre when the doctor mentioned it to me is to not lay down directly after taking it. He said doing so allows the medication to sit on the stomach lining and can cause irritation so give yourself 15 minutes to half hour before you lay down. Sounds crazy, but I tried it and it did help a lot! You could also ask if you should eat something with it.
Good luck with the baby when you try! That's an exciting time and I can't blame you for wanting to hold off on the other meds for now. As far as the liver problems with Rebif, I do believe they do regular blood tests to check for that. Hang in there!
