I find it somewhat difficult, but it's not too hard to balance it all though. I do get jealous when some of my single friends talk about not having gone to the grocery store or cooked in weeks because they don't have time...while that's something that I basically have to do for my husband and I.
Anyway, as far as a schedule goes I mostly study at home. My husband also has a busy schedule so I usually get home before him and study for an hour or 2. Then, when he gets home, one of us cooks and we eat together. Then, I go back to studying for another hour 2. At the end of the night sometimes we watch a little tv together, but that rarely happens.
The week before the test I tell him I'm basically off limits and won't be cooking or cleaning because I pretty much study around the clock.
As far as household stuff goes, even before med school we were pretty good about dividing chores up evenly, so we still do it that way. I still do most of the grocery shopping, but sometimes he comes with me and it's nice to get to spend that time together even if it's at the grocery store.
I'm so glad I have him to support me though!
