If you've already decided that PhD is not your thing, I'd suggest you to talk to your committee members, stick to whatever you're doing for one more year or so, and graduate with a masters degree. That will give you time to figure out what you'll be doing next. You might even find a job by then.

I agree with most of what junkyfunky said. Science (especially biomedical sciences) isn't for people running after money or comfort (at least until you're done with your postdoc/fellowship/residency or an equivalent training). Either learn to like it, or move on to a different lane. You WILL NOT be able to advance your career if you're not passionate about what you're doing, regardless of the field you are in.

I'd suggest anyone who's going through 'i'm not really sure what i want to do' to consider an industry based career in areas like IT, business, engineering, etc depending on your interest. You'll save yourself a lot of time and effort.
