This is normal for a lot of people, but it is not ideal, and there are things you can do to improve the situation. While I agree that seeing a doctor can be helpful, there may be other simpler and cheaper steps you can take to improve the situation.

First you need to answer these questions:

1. How long has this been going on?
2. Has it been every morning or random?
3. How many hours of sleep are you getting on the days this happens vs the days it doesn’t happen?
4. What is your sleep hygiene like?
   1. Is your bed comfortable for you or do you wake up in pain?
   2. Is your room completely dark or is there light pollution - especially blue light?
   3. What have you had to drink and eat in the hours before going to bed? Have you had any alcohol or caffeinated drinks?
   4. Are there any other disturbances in the evening, like pets in the room, small children, or getting up to go to the bathroom, etc?
   5. Do you look at your smartphone or computer screen within an hour of going to sleep?
5. Are you frustrated by things or thoughts that occurred the previous day, or perhaps worried about the day you are beginning?

​All of these things are known to negatively affect your sleep quality if you don’t control them, and they can have the effect of leaving you feeling drowsy and sleepy in the morning, even if you don’t perceive a problem with any of your current habits.

Get the answers to these questions for yourself. Tackling them one by one will help you fix the problem. Some may even be fun and improve your life as a whole.

If fixing these things doesn’t help, you will still benefit from having these answers to give to your doctor. Doctors typically don’t have time to go over your personal history and consider all these factors during a 15-minute appointment. If you have these answers at the start, you will be giving yourself the best chance of fixing it.

Hi, in general what you are describing is not a good sign. These occurrences are your body telling you that things need to change, and there can be serious long term consequences to not giving the proper attention to your body’s sleep needs. Do what you can to change your programming schedule. Studies have shown even small amounts of light (like that from a computer screen, or even on/off lights on appliances), at night, can have a real negative impact on your sleep quality. Read this article [1] for more information on how this works.

The sooner you can get to a more regular sleep schedule, while protecting the quality and quantity of your sleep hours (aka - sleep hygiene), the sooner you can have the better state of mind and body you want during the day.

Nutrition is also a key factor in getting better sleep that is often under-estimated. Be mindful of the quality of food you consume, limit sugary drinks or alcohol, etc. This will also help you get better quality sleep and feel better during the day, whatever time you choose to go to bed.
