Drink the water ! ! It ' s definitely allowed overnight . I was diagnosed at 18 w , now almost 33 w . I have been diet controlled but pretty sure I ' m starting Glyburide in the next few days because while my post meal numbers are still fine , my fasting numbers have been creeping up . It ' s not Your fault . It ' s the way your placenta is interacting with your body . Timing and spacing out snacks Is a pain in the ass . It helps to track on something like My Fitness Pal , because you can check the carb content before you eat something it helps plan what you can have . Balancing the carbs with fatsproteins definitely helps with processing them . Basically just pay attention to serving sizes that ' s a huge deal and you ' ll prob just have to change to 100 % whole wheat bread instead of whitepotato , whole wheat pasta instead of regular , sweet potatoes instead of white , brown rice instead of white , etc . It ' s a Lot of trial and error , what works for one person might spike another . I use dark chocolate covered almonds as a snack to get my sweet fix , and Swiss Miss makes a no sugar added hot chocolate packet I make with whole milk that hasn ' t betrayed me yet . perfect for the coming winter . I Do plan on splurging a little today , and my baby shower , and on Christmas . I will have a small slice of pie and a small scoop of regular mashed potatoesstuffing , and I will track it and not worry about it if my numbers are a little higher than normal . One bad day is not going to hurt as long as it ' s rare . You ' ll figure out what works for you soon enough . Good luck !
