Talk to General Physician on Lightheadedness & Dizziness

I've been working in night shift continuously for last 5 years, I sleep usually after 6 am but take sleep of 8 hours, my sleep is not continuous because of kids and daytime house chores but more or less I sleep for 6 hours. For last few days, I am feeling lightheadedness and dizzyness after 3 - 4 hours of waking up that continues for the entire day.

I wake up fine but after a couple of hours, I start feeling drowsiness first, yawning and stuff, then the lightheadedness starts. The condition is similar as you wake up in the middle of your sleep, so you cannot focus properly, your concentration level is low, your grip and hand to mind coordination is slow. This is what happening to me after I wake up and it continues for the entire day.

It is not very severe like spinning of head but my concentration level and hand to mind coordination gets low. Is it because of sleep deprivation or any issue that I need to consult with a Neuro for?

Please advise, I am not taking any new medicines and
