Has high blood pressure and high cholesterol and sleeps too much. Does the sleeping have anything to with blood pressure?

No. High blood pressure is silent. The meds, however, could be causing the problem. What medications are you on for this?

Mine can go over 225 at times and I feel like utter crap.
(Have to lower it with diet, not drugs. They have all caused horrible coughing so far.)

In all things, it is relative, How high is it?

But yes the drugs you take can cause sleeping, sex and other issues.

Also, when I used to be on some of them. (not on them for 3 years after my change of diet and exercise) But I had to change them every 4 to 6 months due to coughing also.

A type of blood pressure meds called ACE Inhibitors can cause a cough in some people. Not all blood pressure meds causes this, there are other meds that don't have this side effect. A change in diet is good, but doesn't eliminate increased BP for everyone. I, for one, changed my diet and list almost 40 pounds, but still have high blood pressure.

The 2 that caused coughing in me (intense and right away - it's a sign that your kidneys can't excrete the kinins (byproducts) so they end up in the lungs) were Lisinopril, an ACE inhibitor, and Norvasc, a calcium channel blocker. Lisinopril was much worse, but I took it for 3 weeks, and Norvasc for only 6 days.

Blood pressure levels rise naturally and fall into a circular pattern throughout the day. They tend to peak in the middle of the afternoon, and reach their lowest points in the middle of the night during their deep sleep. Now in this study, participants with sleep restriction recorded an average of 115/64 mm Hg at night, while their well rested counterparts recorded an average of 105/57 mm Hg. In addition to confirming that inadequate sleep limited the predicted decrease in blood pressure with these figures, the experiment revealed a higher nocturnal heart rate in subjects with sleep deprivation than those who experienced normal sleep.
