last night i put the 20 mm peridise in and went out to the garage to watch the red sox--posts have mentioned wearing it while watching tv but if didn't work for me--too much clothing restriction and pressure from the chair--thie next morning i put in the 20 mm but after initial movement it became stuck--had a bm and reapplied--better but still not satisfactory so took it out and put in my mgx--hadn't used it much since my peridise came...
