I graduated in 2011 with about 185K in loans. Didn't really start repayment until after residency, so last year. Have paid about 50K off in that time. I also paid off my car loan (18K) in that time period.
The key things that helped me were:
1. Started an MTM business during residency and got a very big contract. I Volunteered to take on extra patients at the ends of quarters (October and December) and made an extra 5K and 20K, respectively. My total earnings for the year were greater than most pharmacist salaries, and I only did it full time July - December. From those earnings I only paid myself $2500/month and saved the rest to use for debt reduction (and taxes!).
2. Was able to deduct some expenses like cell phone and internet because of the business. But this was really very minor because we got murdered on taxes anyway.
3. Picked up extra work doing writing, editing and web site management projects. Also worked PRN at an independent from July - November. I saved every penny that I earned at those jobs. I also taught an MSN pharmacology class and saved that money as well.
4. Did not substantially upgrade our lifestyle. We have lived in the same house for 12 years and the mortgage payment is very low (around $500). We did buy a used Honda Odyssey (still very expensive by my standards!) in May 2012, but I paid it off a few months ago.
I would have earned more at some of my side projects, but I took a month off from everything but MTM during November and December because I had a baby. I've been taking it easy since then, and only working part time at Target, PRN at a clinic pharmacy, teaching my spring semester class and doing some writing/editing/web site management. I am taking the summer off from teaching and considering two different full time positions (similar pay). I think we should be able to get to our goal of < 100K in loans by the end of 2013. 👍
