So I have been succesful with PM and going to switch to BO after my 12 day vacation.

Apparently its pretty easy for me to get Finasteride (1mg) or Dutasteride (0,5mg) prescription. 

Anyone have any experience using these with BO?

No personal experience, but Dutasteride is excellent DHT blocker which does more than one thing at once, so that's something I'd consider if I were you. Fina might cause withdrawals and some side effects if in long term use.
