I just started PrEP on Saturday. It's been about a 4 month process before first starting to talk to my doctor about it (thankfully a great gay doctor who is very up to speed on the latest research) and taking the first pill. I'd contact your insurance company first or getting on a free/reduced cost copay to avoid any surprises at the pharmacy. My first insurance plan didn't cover Truvada as PrEP so I had a $1500 copay... Needless to say I didn't pay for it, spent a few more weeks researching new health plans and then once I got a good plan, needed to do all the HIV tests over again. But, no side effects and am looking forward to no longer freaking out about random hookups. Good luck!
