The sleep study described by the viewer indicates lack of deep sleep (REM sleep). Lack of REM sleep can contribute to fatigue. While any medication can have side effects and affect sleep, Accupril and Cardizem are not known to affect sleep pattern and sleep stages.
There are many abnormal sleep patterns. The most common sleep disturbances are 1) increased arousals related to intermittent upper airway obstruction--thus disrupting sleep, and 2) periodic limb movements (restless legs) disrupting sleep. Fatigue can be related to lack of REM sleep.
The viewer should review the sleep study with the doctor. Also work with the doctor to exclude other causes of fatigue such as anemia, thyroid disorders, medications side effects, etc.
