I'm making tincture using the hot extraction recipe. It still smells a little like rum. Should I leave it in the hot water bath longer? And, when it says an eyedropper... How much would that be? I don't want to pass out, just feel good.
Leaving the jars in hot water does not change the properties of the alcohol like cooking with it does. An eyedropper is usually 1mL I believe. I would just start with 1/2 teaspoon, wait 2 hours, then take another 1/2 teaspoon and see where that takes you. Dosing too much at once is not pleasant 
Many people add sugar extract flavorings to them, like watermelon. I personally just add 1 tsp to a drink and thats it.
