I'm finishing a graduate degree and I have a house to sell and kids and a husband to help transition, so I'm pretty booked up until late May...I'm hoping to have a relaxing June/July once we move before med school starts. It will be my first summer "off" since 2013.
If you're still in school, finish strong. I gathered you're not though since you said this is your 3rd app cycle. Congratulations, your perseverance has paid off! If you're working, stick as much as you can in the bank so you're less poor during med school. Get your house in order over the next few months...learn to cook, clean, meal plan, budget, get into a good routine at the gym, declutter so you're not taking much with you if you move. Once you've got all that handled if you still have free time (and money), travel a little, see family and friends before you move and med school takes over your life, read books for pleasure, and watch all the TV shows and movies you've missed trying to get into med school.
Oh, and bask in the acceptance for a little while. 🙂
