Tea! Or something similar if you don't like tea. My husband and I try to identify (and update) what makes us feel close to each other, and we often realize that we waste a lot of time that we're together. Even just 15 mins - a little tea time or something of the sort - as long as it's 15 mins that we are really focused on checking in with each other and how we're doing, goes a long way!
We also try to stay in the habit of a weekly "business" meeting - a time where I can express to him what's been on my mind (like if I want to try to buy new curtains next week) and hear what's on his, and try to set a small weekly goal to work on - like wiping off the kitchen countertops after you make a snack.
And lastly, we try to make the most of time we're in the car together - time to communicate, and we try to pray together every time we're both in the car. We also make our weekly grocery shopping into fun family time.
That way - here and there during our days, we can stay connected on a communication level, and then the nights when we are able to go to bed together at the same time - are available for connection on another level
