Time of taking meds ?

Hi,

I've recently been told my BP is quite high (I was actually admitted to hospital after my doctor took it - 210/150) and now I'm on 4 different tablets to try and control it and its working - to a point.
I still get ringing in my ears which gets better and worse but never goes away.
I still feel quite fatigued alot of the time but I recently had a major operation to remove a tumour so that's not helped this matter.
My BP, like some of the other posters I have read here today, my BP is higher at night and sometimes it disturbs my sleep. If my BP is too high then my bladder goes into overdrive to get rid of excess water to try and get my BP down and of course being tired just makes everything more stressful which pushes up the BP so it's a vicious circle.

My question is this - does it matter when I take my medication?
I take 3 ACE inhibitiors and a water tablet first thing in the morning and 1 ACE inhibitor in the evening.
Would it matter if I took the 'first dose' (the 4 tablets) at say, lunch time or dinner time and then the 'second dose' at breakfast or lunch?
As long as I take the tablets every 24 hours, does it really matter when they are taken?

Any opinions would be appreciated but obviously I'm going to see my doctor and explain whats going on and ask his opinion too.
