I have just started my first pen, bought from Asda. I am 12st 4, BMI 30, and want to lose nearly 3 stone to get to 9st 7 (I am 5'3). My bmi would be 23.7. Reading the threads, I'm worried that Asda will stop prescribing when I reach a "healthy" BMI of perhaps 26, which would be 10st 7, a full stone over my target weight. Anyone else with Asda who can advise? I prefer to stick with them as I can collect from pharmacy, but am wondering if I should switch sooner rather than later? I know that 9st 7 is a good weight for me as I've been there before.
