I Have A Terrible Dry Cough That I Know Is

I have a terrible dry cough that I know is caused by one of my medications.... I just don't know which one.
I cough so hard that I throw up and can hardly catch my breath. I keeps me up at night and I make a special of my self when out in public. People ask me if they should call an ambulance.
I take venlafaxine ER 75 MG (2 caps daily)
spironolactone 25 MG (1.2 tab. daily)
Losartan 50 MG (1 daily)
Chlorthalidone 25 MG (1 tab. daily) and
Levothyroxine 50 MG (1 tab. daily)
Had to quit taking Lipitor because it caused the same harsh cough. I just can't live like this...please help me.
