In my experience I had to self advocate, I told them I'd self medicated 2 years before. And I also told them what doses I was taking and such. They seemed pretty clueless but I would hope that it is a bit better now. (I was also going through the NHS at the time, and I had one of the worst experiences going through their "system") But I do hope you get someone nice and with some previous knowledge..
