Local worked for me …
Had the cath during the sct program as it uses the same machine to harvest the stem cells as they use for PE – similar process, blood in, blood out. Everyone in our group had it done with a local and no one complained, including me 🙂 , so think you should be OK.
I was in a little longer than you will be, but I read the entire Harry Potter series. It was a hoot!!! I like to do that – wait until all the books are out then read them all. So you might pick a series and go through it? I also took my laptop with me and skyped with various friends daily – even played some yahtzee via skype! It all helps with the boredom. And you will probably get bored fast as I suspect you will feel better fast!
Of course, you can also keep us updated and that will take a little time. 😀
