Hi there every day after work, I have a couple of drinks (red wine), which helps me to sleep until around 2AM. Then I have to wake up and take a pee. Then I stay awake for the next 1 or 2 hours, before falling sleep again.
Are there any supplements, or health tips, which can help me sleep tight for the whole night?
Based on my own experience, avoid the alcohol. If you're using that to help you get to sleep, there are better ways - I find a bit of exercise (even just a 10-15 minute walk outside) and Melatonin tablet (about 30 minutes before going to bed) help me to fall asleep, and more importantly, stay asleep.
Valerian is also traditionally used to help promote restful sleep and is in many calming/sleep teas and the like. These do work - I was sceptical for a long time but have found a combination that works for me. After using alcohol for too many years, it's made a huge difference in my life
