I wish Coffee would do more

Over the past 2 weeks we have had alot as a family going on. My husband just started a new job with a new schedule, and its going to take awhile for us to get used to it. I play taxi driver to everyone now which saves us on parking and gas at least, but I am exhausted. I literally have been drinking coffee hoping that the caffeine will perk me up, but caffeine has no affect on me or at least I never feel it. I at least like the taste. But when you are up in the middle of the night off and on with an almost 3 month old, then up at 6 am. Then you drive everyone around finally get back home about 9 something. I am ready for a nap. The bad part I can never get a nap. The baby will be out in his carseat, my 2 year old is wide awake and not ready for a nap until 11. So I am up cleaning, organizing, and playing with the kids all day. Go and pick up my oldest son from school, and its like hyper city here when he gets home. By 5 I am picking up my husband from work come home and try to get dinner going. Then its showers, or nagging kids all night. By the time the kids are finally in bed I am sitting on the couch like a walking zombie. Both my husband and I are looking at the clock by 9 asking ourselves if we should go to bed that early or try to stay up. It's been half and half on the results. I will say I have been asleep pretty fast, usually it takes me hours to fall asleep. Then I wake up and again I am ready for coffee and hoping it perks me up. 3 kids definately keep me running, 3 boys I would say the freaking keep me running constantly, 3 boys and playing taxi driver, I want more coffee please!!!! I am so ready for the weekend!
