title: I just read that the time of day or night you take certain blood pressure medications can have a lot to do with how effective they are.  In particular, I noticed that ACE inhibitors, which I take, are much more effective if taken before bed.  My doctor never told me that.  Is this true and what difference does the time of day make?
