It took me almost two week to get used to the zoloft. After that I felt much better. I also had side effects coming off it too. Good Luck!!
You should start feeling better in a few days. Cymbalta may be a better choice for you. I'd talk to your doctor about changing meds. Good luck!
If you have tried zoloft a few times without success then you should tell your doctor and he can try another medication that may not have the side effects you experience. Many medications have side effects which seem bad in the beginning but subside in time. Sometimes it's better to start on small doses and build up more gradually. Hopefully you are seeing a psychiatrist for medication management as they are the best equipped in dealing with these medications.
