Diltiazem
"I had been on Diltiazem CR (controlled release) 240mg per day, took it every morning faithfully. I am now in Spain where they do not have the controlled release but gave me Diltiazem regular release 60mg. The first day I took all four at once in the morning and it dragged me down so far I about collapsed. Now, I'm trying to regulate it, taking one 60mg in the morning, then one at noon, then one about 4pm, then one about 8pm.

I have heard that some blood pressure medicines shouldn't be taken before one goes to bed. Does anyone know about this one?"
