Medications effect everyone differently so it is impossible to know how they will effect you. Just try them and monitor how you feel each day so you can report it back to your doctor. Sometimes there are side effects that only last for a few days as your body adjusts to the med so it is worth persevering for a week if you are having side effects. Of course, if the side effects are causing you harm then stop the med. I have tried nearly 20 different meds over the years and most had little side effects. A couple had bad ones that passed in a few days and one was disastrous.
With the symptoms you are experiencing it is worth giving the meds a try as it must be awful feeling the way you do. Hopefully they will give you some relief. If not there are plenty more you can try. Sometimes it takes a while to find the right meds so be patient.
