I'm going to disagree slightly with TP's answer:

If you are being paid by the hour, then yes, you need to discuss this with management. They may be able to take some of it out of your sick time or vacation time, or may just cut you some slack if your productivity is high enough during the hours you are awake. If you can eat while working, you may be able to use your lunch break to nap. But you can't bill nap time as hours worked without some such arrangement.

If you are on salary, you should still discuss this with your manager, but they have more options. They can decide that what they are really paying you for is productivity, and that if you are still getting the job done well (including being responsive when they need you), when you get that done doesn't matter so much. If you can accomplish in fewer hours at the desk everything that you did in a full day, or at least enough to get a "meets or exceeds requirements" perform rating, that may be good enough for now.

Having been through two periods of medical exhaustion myself (severe depression, and heart attack recovery), I want to offer some coping strategies even though you didn't ask for them:

1. Try doing meetings while standing. Or try taking detailed minutes during meetings. Either may help you stay focused. Getting up and moving around a few times during the day can also help maintain overall alertness.

2. Try shortening those naps. Set an alarm. A half hour may be all you really need. And as noted above, you can nap on your lunch break and eat at your desk...

3. Make sure you are getting enough sleep overnight. That probably won't eliminate meeting fatigue but it will help with (2).

4. If not medically inappropriate (ask your doctor), caffeine before the meeting can help. Try not to caffeinate in the several hours before bedtime.

5. Have you spoken to your doctors about this? They may be able to adjust medications. In my case, we were able to reduce one which tends to cause drowsiness while increasing another which tends to be "activating", reducing side effects overall and improving my ability to stay alert through meetings.

6. On antidepressants, there's a notable difference between "it's helping" and "hey, I finally had a day when I felt good again", which seems to be a combination of dosage and time. It may take some work and adjustment, but it can get better.
