beginning IVF soon.. single embryo transfer.. PGS testing?

Jessica
Hi all, 
I need opinions on a couple things! 
I am going to start my first IVF cycle in a couple weeks! 
I have PCOS, had a LEEP procedure to remove abnormal cells on my cervix, so my doctor recommends a single embryo transfer. Which brings me to my first question: what is your opinion/experience with genetic testing? I am only 30 years old, no known genetic abnormalities and have never had a miscarriage. I'm not sure if paying the extra $6,000 for this would help me or if it's going to be worth it. I know that since we're only doing one embryo, we want to make sure we put one of good quality. Any feedback is appreciated :) 
My second question is: WHAT ARE YOUR IVF SURVIVAL TIPS!? 
What is best to eat, to drink, to read, to DO! Anything! What helped you survive the IVF experience? 
Thank you!
