I have. I put that back on the other day as soon as you advised me to. When I got the results last Wednesday evening I took the patch off. When I came home after the doctors on the Thursday morning I put a new one on so i was approximately 14 hours without a patch. I haven't used the gel though since last Wednesday, the evening I got the results, and I only use 1 pump every evening. Test at Nuffield was this Tuesday morning.
