Should I stay on sertraline?

I just started Zoloft a week ago. I had a horrible time on 3 weeks of Prozac - transitioning from Lexapro to Prozac was very unpleasant. All of this unfortunately is normal. I feel like a guinea pig right now but it's important to get it right. All of these things come with these types of drugs. Try to be patient and see it through. I know it sucks.

Hi, milemol!
This type of medication does not act quickly or overnight like many standard drugs. Most people will begin to feel improvements in the first couple of weeks and it may take 4-8 weeks for the drug to become fully effective. Also, ironically, it can cause increased anxiety for the first several days to a week or so.
That being said, if you can try to be patient and maintain a positive attitude for a while you'll probably find that this medication will change your life.
Do things to distract yourself if you can... take a walk, read a book, watch a favorite movie. Try meditation and/or deep breathing when your anxiety symptoms hit.
Best regards and I hope you're feeling much better quickly.

Starting the meds and finding the correct dose is very difficult. When I started I felt just like you are feeling now. It took several weeks for the medication to settle into my system and be effective. Don't give up. It is worth it. Try not to read the stories of other people right now. We are all unique in what works for us. Stay in contact with your doctor. Also try to eat something. Maybe meditation and also be with people that help you feel grounded and safe. All the best to you.
