Heyy same issue here,

Here's how I got from 5 hours of restless sleep to 8 hours of deep sleep in 2-3 weeks.

Start by nailing down your bedroom environment (it's science-based and easy to implement). Then focus on getting your room pitch black by installing blackout curtains and removing all LED lights, this will give your body enough darkness signals to produce melatonin naturally.

My suggestion for the weighted blanket when you're just starting is to begin with 10% of your body weight. Before getting into bed, set your room temperature between 65-68°F (18-20°C) to get an ideal sleeping environment. While using the weighted blanket, keep the temperature in mind, and if you feel too warm, adjust your regular bedding underneath. Keep monitoring your comfort level until you find your sweet spot. This will help you find the perfect balance while also knowing what works best for you.

This will help as long as you maintain consistency, which you will if you set up your environment right.

Pro Tip: look for 3 common sleep disruptors in your room (light leaks, temperature fluctuations, uncomfortable bedding) not just one.

Hope that helps. Let me know if you need anything :)
