Poor lad lol. Look, personally, it looks like you just want a straight answer with no preaching. You obviously understand that medicine is very competitive so you need a good fall back just in case. It IS hard to choose between courses when they are not your first choice ad you have other things to research.
Personally, they both seem well paid. Pharmacy may be more secure to be paid well at, although I don't know about how they compare on prospects. Good luck!
