I thought I was pregnant once, and the test I took was a digital one. I couldn't deal with trying to decipher lines. I seriously was 100% convinced I was pregnant, and of course, I was not. Thank goodness! My mom said the biggest clue to her she was prego was sore breasts.

Now, as far as your cravings -- you are taking in a lot of sodium! You should try to drink as much water as possible to make up for that, so you don't get dehydrated. Dehydration can cause headaches. Sodium can lead to other scary stuff, like hypertension and high blood pressure, on down the road. As far as being tired in the middle of the day - if your Wendy's sodas are caffeinated, that could have a lot to do with it. Caffeine energy crashes and withdrawal headaches could be happening to you if you're drinking caffeine in the AM, and find yourself needing more later to keep yourself going.

I just recently started a new eating plan and I am amazed at how much better and overall more healthy I feel. Now, this is not to say I do not get cravings. Chocolate and peanut butter cravings hit me every single day. I want a Reese's Peanut Butter Cup so bad I could die - I've been craving one every day for the last two weeks. I had a homemade chocolate brownie on Valentine's Day instead -- and I thought I was in heaven!!

I agree also with whoever said it could also be boredom/cabin fever. Whatever it is, I hope you feel better soon!
