You are ill-advised to get testimonials from strangers on the Internet about medications.
Anti-depressants are one of many groups of drugs that work differently for different people. There are dozens of top prescribed anti-depressants...and some work for some while others work for others. Some people experience side effects with one, others experience no side effects whatsoever.
An individual's experience with a certain medication depends a lot on their metabolism, age, physical condition, medical history, dosage, and the severity of their problem. Your doctor will work closely with you to monitor your Celexa and the dosage to be sure it is right for you and to get you to the proper blood level to be maintained for maximum effectiveness.
It could take several weeks to kick in but Celexa is a newer drug and is prescribed for those who have had problems with side effects of other drugs and for those with thyroid dysfunction.
The standard side effects of anti-depressants, and not all people experience any or all of them, are dry mouth, constipation, mild to moderate dizziness, anxiety, etc. You can expect a little of this at first and then those side effects usually go away with time. If you start feeling really weird, call your doctor for reassurance.
Rather than exchanging war stories with people on the Internet, you are strongly advised to talk to your doctor about what to expect, especially if you are feeling anxious. You are on an excellent medication that has helped hundreds of thousands of people.
If you want to read about the drug from authoritative sources, go to a good search engine like:
www.google.com and enter the word "Celexa" in the subject field and knock yourself out. There's enough material about Celexa and depression on the Internet it will take you some years to read it all. That's only if you must. Certainly you have other interests or better things to do.
You hired your medical doctor to deal with the problem for you. Since you do not have a working knowledge of general pharmacology, you are likely to misinterpret a lot of the data you may read on the Internet...and certainly misunderstand what people might tell you about their own personal experience with Celexa.
Please talk to your doctor if you are having any doubts or misgivings about your medication.
