Getting a PICC inserted takes courage - kudos to you for going through with it. Your health is at stake so be strong. I'll be with you tomorrow, holding your hand through the whole procedure. So no worries.
When I had my PICC line inserted and I began IV Rocephin, my LLMD put me on Usodiol to prevent any gallbladder damage. It worked great - I had no trouble at all. I think Actigall is a similiar drug.
No matter what drug you take (I am on IV Zithromax), try to remember that Herx's are a good thing since they are proof that the drug is kiling bacteria.
You may feel like crap but the stupid bacteria feel even worse 'cuz they're dying.
Good luck tomorrow, let us know how it goes!
Peace and health to you,
