Avapro and coughing

I am taking Avapro for HBP and since taking it my FREQUENT migrations have disappeared! The problem I have is now when I lie down at night to sleep, I always wake up with a terrible coughing fit. There is a "gurgling/bubbling" noise coming from my stomach (when I open my mouth and "listen"). Once I stand up and walk around a bit the coughing stops. I have heard that some Blood Pressure medications cause sever coughing fits. Is this a side-effect of Avapro?
