Need your tips for overwhelming fatigue!

jo

I'm only 4+3 with my second, but this sleepiness is kicking my butt! I might also be overwhelmed with my first starting kindergarten at an annoyingly picky school and with my new stubborn breed puppy needing so much training, not to mention the freelancing business I'm trying to get off the ground, and general daily housework (plus frantic spring cleaning since the MIL is coming to stay with us). But some of this fatigue has to be the pregnancy, lol. I'm pooped. Any pointers? What can I do to feel less tired, besides sleep?
