You should get yourself re- evaluated for sleep apnea and maybe discuss the use of a CPAP machine at night.
Have you got an ECHO done? Your blood pressure should also be in the normal range and medication should be
titrated accordingly - do not alter the dosage or stop medication without consulation with your doctor. For
the memory loss you are experiencing - this could be due to high blood pressure, fatigue, work related stress
- this is usually transient. Just calm down and relax and hopefully your symptoms should go away if you sleep
well. But if they persist, consult your doctor for a detailed evaluation.
