You are responding to the antihistamine in the Ny-Quil which is a sedative. It's the decongestant (probably psuedoephedrine) which is contra-indicated with HBP.

Check the bottle for diphenhydramine (Benadryl) or chlorpheniramine maleate. One of THESE is the sleep aid (not sure which they use.) Go to your local DOLLAR STORE and buy a generic with ONLY this drug...sleep like a baby.
Why take a mixed med with 5 ingredients to get the one you need.
Personally I HATE the fuzzy hangovery effect of the diphen... but MANY people are taking it regularly for sleep.
