I am taking Xarelto 20mg,Metoprolol 50mg, Valsartan 320mg and Amlodipine 10mg. I am always tired ,sleepy, and have very dry mouth in the morning. Also, I feel shortness or tired breathing in the morning. I have a fibrillation. I would like to know if any one of medicines above would cause those symptoms. I will appreciate you advise or recommendations. Thank you
