Hi Ed. Reading your post has taken me right back to my experiences of dealing with the mask. I found the fitting of the mask pretty horrible and I was worried about being left alone while the raditation was underway. But once it was underway I got into the swing of it and found I could let me mind wander in quite an 'out of mind' way. Lying so still is a bit strange as after a while there is no sensory perception telling you where your body is in space, so I felt like I was floating! The mask did feel tight to start with and left pressure marks on my face for a few minutes, but it felt more comfortable as time went on. To start with I just focused on my breathing. I hope it goes OK for you. Trying pre-thinking of some pleasant thoughts to focus on. Sally
