First things first, I fully suggest heading to the doctor. Feeling faint after eating/drinking coffee can be your blood sugar or your blood pressure bottoming out. It can be a myriad of other things too [1], some quite serious. I'd mention your low energy levels to the doctor as well, as it sounds like it is worse than normal. I think taking care of this will make a big difference in your energy levels. As far as other things you can do, it is really all diet, exercise, and consistently getting good sleep. I eat most of my food in the evening because I'm not hungry in the morning. I drink a cup of coffee sporadically through the day (rarely do I have two cups in a row). I walk as my main form of transportation. This stuff is more likely to give you consistent energy levels from day to day, but it won't even out some of the ups and downs throughout the day. You mentioned dehydration: I had a spell where I was getting a bit queasy and dizzy through the day. I called the doctor, and the nurse held off on making an appointment because it sounded like dehydration. It is something you can get over fairly easily. Her instructions? Take it easy for a day. Eat healthy foods. A banana is especially helpful (potassium). Drink lots of fluid. It should get much better that same day - and it did. Otherwise, off to the doctor with me, but luckily that didn't happen. Good luck, and I hope you get feeling better.
