Your dad is taking several medications that can cause drowsiness.  If you think these medications are causing your dad to sleep more than he would like, he should speak to Dr. Davis about alternatives.  He can also try reducing his caffeine intake, which may help reduce his drowsiness.  You can also help reduce some of your dad's early morning grogginess by letting him get at least 8 hours of sleep each night, and by giving him gentle physical activity rather than hard exercise in the early morning hours.

That is understandable.  Many of the meds Dr. Davis gave your dad should help his symptoms.  And it’s common to experience sleepiness as one of the side effects of these types of medications.  The key is for your dad to find a good balance.  While he shouldn’t be driving or operating heavy machinery if he feels sleepy, it’s okay for him to take a nap during the day.   You can also try helping him manage this side effect by avoiding stimulating activities during the day (for example, do not give him coffee or caffeine) and stay home from

Does dad sleep a lot due to his medications?

Many of the medications Dr. Davis gave your dad might cause drowsiness and make it difficult for him to stay awake during the day.  This may make your dad feel sleepy and tired, and sometimes cause him to take naps during the day.  You can help him manage his sleepiness by avoiding strenuous activities, and by avoiding giving him medications that are activating, such as coffee or caffeine.  I know that may be difficult with your homework and schoolwork, but speaking to your teacher about these new demands your family is facing may help.  If your dad is having a particularly difficult time staying awake during the day, you can ask Dr. Davis about alternative medications to try.

He stopped drinking coffee since it made him vomit. So he is not as awake anymore. He takes Lexapro and blood pressure meds which cause drowsiness
