I've been in induction for 3 days and I've had a bad headache.. I know it's from lack of caffine... I've been taking excedrine but it's not doing any good.. IB profen wont do anything. I had to leave work early b/c I couldn't see from my headache. My husband bought me a diet soda b/c he couldn't stand to see me in pain. My question to you all is, what's wrong with one can of diet soda a day. I believe I get my daily intake of water.. I'm not sure because I work outside and I drink from a fountain... Any suggestions??
