I Have Rheumatoid Arthritis And Am On The Following Drugs....Enbrel,

I have rheumatoid arthritis and am on the following drugs....Enbrel, mobicox, plaquenil, and I am also on the following drugs...valsartan, ezetimibe and nasonex as well as apo-mometasone. I feel drowsy during the day but it doesn't bother me when I'm busy. As soon as I sit down and am very still I fall asleep. I work really hard to stay awake it to no avail. I also have a hoarse voice. Could these drugs cause either of these things?
