How do I get a better night's sleep, instead of waking up constantly in the middle of the night?

There are many different ways this can be done, and it's important you see which ways are best for you. Here are a few ways: try to exercise every morning or afternoon (not at night), try not to eat a heavy meal before bedtime, drink warm milk before bed, take over the counter melatonin to aid your sleep, meditate and relax before bedtime, try to avoid being on your phone, laptop, TV, etc. 1 hour prior to your bedtime, and make sure your room is a comfortable temperature for you. If these don't work, I would advise going to your doctor to see if you have sleep apnea or if they can prescribe you a sleep medication.

It depends on the reason you're sleeping not well, but in general, it helps when you go to bed and wake up at the same time each day. It also helps if you use your bed(room) for sleeping only, so no television, laptop, phone,... in bed. When you wake up at night, don't look at the clock and count the hours you can still sleep, because it will prevent you from falling back to sleep. When you're awake in bed for a long time, it's better to get out of bed and to do something else. When you're feeling tired again, go back to bed. This way, you can learn your body to link 'bed' with 'sleep'. Hopefully, some of these tips will help you. Feel free to ask more if necessary!

First take a hot shower or do something you enjoy to de-stress. Then calm your thoughts and relax. Try to imagine something to make you tired like maybe counting in your head or visualize an ocean. You can also try sleep aids like Zzzquil and even white noise (like a fan or white noise machine). I personally take sleep aids + use a fan sound from Youtube that plays for 10 hours. Also if you are uncomfortable you won't sleep so find some comfy clothes, the right room temperature, maybe cut off all lights (even use black out curtains) and stuff like that.

Be in dim light at least one hour before sleep. Don't work with your phone before bed. If there is anything in your mind right it somewhere and say this is my tomorrow's problem , be comfy , good clothes and , you can always get help from asmrs , instrumental musics , go to for example relaxing ambient vibes on YouTube and check it out. Sports during the day can be really really helpful , good scheduled sleep time also helps. Your brain must expects the time you are going to sleep. And that was all . .
