I find yoga really helps both in the morning and at night. I was really reluctant to try it because I saw it as one of these new age fads and I also get reAlly self conscious trying new things in public.
I found some videos on YouTube that were just a few minutes long to get started. There's loads for different effects (like waking up, exercise, muscle toning and relaxation) I a found some that I liked for beginners that focused more on the physical yoga than all the aligning energys stuff (it's just not my bag) and did them at home with the curtains closed. I've not managed to brave a class yet but I might in the future. I find doing just 10 minutes before I go to bed to relax helps me get to sleep a lot quicker because one of the thing it encourages you to do is clear your mind and that really helps with my anxiety
