Using Divunis 5 minute meditation video at Youtu.be
has really helped me keep up the habit of meditating before bed recently.
Its short, relaxing, and has become easier every day.
If 5 minutes is too short, there is a 10 minute one here: Youtu.be
and a 20 minute video here: Youtu.be
If 5 minutes is difficult with just ambient music, i recommend trying short guided meditations, they can help keep you focused and make the sessions feel shorter, allowing you to get used to it all.
