I could have tried it, true, but I was furious by his attitude, that I even stopped consulting him unless I had some really really bad issues. Why should he or anyone else not give me a choice? I was begging him for an alternative and he denied me that, especially that there's over a dozen different drugs of the type needed for my case.
Luckily for me, he was old and retired a year later, so I had to find a new family doctor. The new doctor I found was younger and way more understanding than the old one. He explained to me in detail the differences between the several drugs he could prescribe and that's exactly what he did. My choice was respected.
