I seem to be my own best doctor but unfortunately I've never had any interest in being a doctor partly because I am squeamish about blood and it seems very stressful.
I had back pain, noticed that aspirin helped but paracetamol didn't, deduced that it must be an inflammation, tried a combined therapy of aspirin and cold water sprays, back pain gone.
Doctor gave me propanolol for anxiety, recognized it as a beta blocker - a medicine that affects the heart, declined to take it because I have a really low heart rate. Another doctor later agreed with me.
More recently my sleep pattern has been really bad but when I stayed up all night and went to bed at 9pm I woke up at 12 am and couldn't sleep again till 6am where I then slept till 4pm no matter how many alarms I set. I was mystified until I thought about what I was doing differently last time this happened and the answer was taking caffeine pills. Seems that taking them to stay up made me unable to sleep deeply when the time came. I decided to use this to my advantage, taking them at 5am just before sleep and for the first time in months I've managed to wake up at 12 pm. Compare this with my doctor who gave me sleeping pills that not only didn't work but gave me nightmares.
In the unlikely event I did apply to be a doctor should I mention this stuff or is it irrelevant?
