My Doctor Prescribed .5 Bystolic Last Month. Since Then,I've Been

My doctor prescribed .5 Bystolic last month. Since then,I've been plagued with stabbing joint pains, mostly at night, dry mouth and throat to where I cannot speak without croaking and am extremely tired all day. I fall asleep without realizing I am sleeping until I wake anywhere from 15 minutes to two hours later. I have trouble staying asleep at nighttime for more than two hours at a time.
My Blood pressure ranges from the low 100's to highs of 130's. I don't think I need to continue this medication and need some ammunition to convince him I can discontinue the Bystolic. I am also taking Amlodipine 5Mg and Pravastatin sodium 20mg.
