What can I do to improve my memory?

It get’s worse. Keep a calendar and write everything down.
Edit. Keep a to do list as well. Use all of your technology for reminders. We’re bombarded with so much info it’s not surprising we lose some of it.

It depends on the underlying reason for the memory issue. Many times eating a healthier diet, getting more exercise and drinking enough water can make a huge difference.

Talk to your doctor and ask for tests that might determine the cause so you can fight that.

8 hr of sleep helps a lot.

I genuinely empathize with your concern. Your need to find out if some medical problem or medication you take is the cause of these memory problems.

It is very true that proper nutrition, physical activity and adequate sleep can make a big difference.

I was getting to that point due to lack of sleep.

Memory is a function of relatedness. To remember things you must relate them to other things you already know. Actively try to create relations, even strange or vivid or fictional relations. I’m not sure if this will solve your problem, but it worth a try.
