Many thanks NiamhM1801, its hard work but definitely worth all the effort. Overhauling diet and finding exercise you enjoy is the key from my experience. I cut out all meat except a little fish once a fortnight, almost all diary except 0% greek or skyr yoghurt, no sweets, milk chocolate and biscuits-I eat natural liquorice like panda, nakd bars for coco fix. I only drink water with the exception of one mug of green tea in the morning and a glass of apple juice with my main meal, alcohol is white wine or diet tonic and gin. I swim 2-3 times a week and have started doing some martial arts once a week, I hope to start lifting a bit again too if my stomach and chest will allow( stomach is the source a lot of my problems).
