I have posted information about BMED a number of times in the past and if you do a search over the past 2 years it should throw up a number of threads. The majority of the information from those is still valid.
If you still have any queries after looking at those then I will be happy to answer them for you. I am away tomorrow for 4 days so will answer them when I get back, for your information I had 3 days off before the trip and will get 3 days off when I get back but it is not normally that cushy!!
