The first exam block was the worst part of first semester and its almost done!
But going to be completely honest, I said the exact same thing about not cramming when it was over....fast forward a couple months and I proceeded to START studying for the histology practical the day before and may have not studied for the first microbiology exam this year until 3 days before the exam.
Definitely try to avoid it as much as possible...but if you need to cram here and there don't beat yourself up because it happens! And if you need to take some time off to do something fun...DO IT!! Even it that means you may need to cram a little before or after!
