I agree about the shakes and bars, the bars especially. And yes, you should be drinking LOTS of water. At least half of your weight in ounces of water a day. Make sure you're eating lots of green, leafy veggies. At least 12-15 of your net carbs per day should come from those. Also, if you will log your food here on FatSecret, it will help you, and others, to determine what the causes are of any issues you may have. Good luck to you!
