I was coughing up a storm at 4 am. I feel dehydrated and a little tired. I think I'm going too apeshit on the iced coffees this time around. If I have more than 12 ounces at a time I actually feel more tired, and unsettled. When I just drank tea I felt so much lighter and more awake. I'm also eating more but a lot of insoluble and soluble fiber, so my digestion is doing great. I just need to keep the water content up.
