Workout ideas needed

So I'm almost 5 months out from my wedding day and have been working hard to get back into shape by drinking more water and working out regularly (I am still struggling with this as my schedule is hectic and I for some reason don't seem to want to get out of bed before my 5:45 alarm...any ideas how to get up earlier (I would love to be working out by 5:15)). However, I have noticed that where I put on weight before getting back into things seems to be my tummy area and I would really like to go back to a flatter stomach before the big day and honeymoon!!!! I realize it may not be possible to spot train, but I am looking for something that will at least help in getting rid of the weight around the mid-section. Does anybody have any ideas or workouts that has really helped with this particular area??
