I am on day two of Citalopram. I started taking only 5mg yesterday. I took the second dose about 10 hours ago and feel so horrible. I feel nauseous, like I am going to throw up, depressed, headache, foggy brain. Will this ever go away? I felt almost fine this morning, went to a country fair, even went jogging. Please respond if you felt horrible in the beginning to give me some much needed encouragement. I am DREADING taking this pill again tomorrow morning. Thank you!
