"i resisted my doctors claim that i was depressed and suffering from anxiety due to chemical imbalance due to being premenopausal. i have always felt in control of my emotions, generally happy and optimistic but for the last year i lost the ability to stay calm and feel happy- my moods kept slipping away from me and i felt angry and sad at the same time. my doctor put my on celexa. my very first dose i had the worst headache i have ever had- i do have periodic migraines but never a headache like this. i continued celexa, reluctantly and made it through the first week. two months later, with an occasional headache and frequent yawning i feel like a dark cloud has lifted. my emotional state is remarkably calm and even a bit upbeat. yea celexa!"
