Chemist looking for non-chemistry work

I'm a current senior graduating with a degree in chemistry from a fairly selective liberal arts problem. The catch is that I really, really do not want a job in a chemistry lab when I graduate. I'm looking for ideas for alternative career options that would be realistic for a chemistry graduate. [more inside]

Getting into chemistry grad school with no chemistry background?

I would like to pursue research in supramolecular chemistry, but I am a couple years out of school and do not have a chemistry background. Also, I lack letters of recommendation. I am certain I cannot get into a decent Ph.D. program, but do I have a shot at getting in a Master's program? Or must I resort to taking classes at a university somewhere? [more inside]

How do I stop attracting the wrong guys and start attracting the right ones?

I was just broken up with by a really decent, kind guy because there was no "spark." He seemed like everything I ever wanted in a partner on paper. I knew there was no spark but I was perfectly fine with that, because it seems like the only guys I ever have mutual emotional chemistry with are either rageaholics, substance abusers, or commitmentphobes. I was more than willing to trade the spark for not being yelled at, put down, or inexplicably blown off. [more inside]

Calling all med students, past and present

Thinking back to medical school classes like Biochemistry and Pharmacology, how much foundational knowledge did you actually use from your undergrad courses in related subjects? Was it important to walk in being able to solve all of the kinds of problems you’d see in general chemistry and physics, or were concepts more important? I am trying to understand how much ‘general’ review is required for success before someone who has been admitted actually starts a medical school program.
