Good luck with your exercise regime. I am taking it easy, but going back and doing things where I previously failed or provoked symptoms. E.g: today I hoovered the whole house wearing earplugs and mopped the downstairs. This is something that would have made me very ill two weeks ago but doesn't now. This is not only rewarding, confidence building, but also improves my stamina. I need to build my stamina to go back to work, and it is a stressful job, but its something I have to do. This afternoon I am heading for the shops! I am going to beat this!
