Question for pegleg

I am on ten different meds for asthma. Some I feel make it worse. Is this too many meds? Am I getting doubles with any of these? Fexofenadine 180mg, singulair 10mg, advair 250/50, combivent, prevacid 30mg, duoneb every 6 hours if needed(if I use this I skip combivent), fluticasone if needed xopenex for rescue inhaler, uniphyl, and benedryl( spelling could be wrong as I take generic). I really feel over drugged here. Help! Thanks:)
