I am a serious coffee drinker every morning at work, however I shouldn't be having withdrawals because I have protein shakes that have caffeine in them. So I'm getting a small amount of caffeine in my body still. Yes I guess I ate a moderate amount of carbohydrates and sugar. I had something similar happen to me when I was low carb program through my doctor's office. I was on very low carb intake and I began to have aching joints to the point where I would lay in bed and almost cry at night. The doctor said it was lack of carbs, calcium and magnesium. Which is why I went and took one of those vitamins right away last night. I feel so much better today. It's probably just carbohydrate withdrawal, sugar, caffeine. I've also been making sure I stay hydrated. Thank you so much for all of your comments. 4 days left! I've waited a year and a half for this and although I'm excited I have been very emotional for the last week. Probably just nerves, scared and a little nervous to go into the OR.
