Could you all please share your experience of weight loss after stopping Quetiapine?

(DISCLAIMER: Everyone is different and will react to this medication differently. My experience of weight gain with Seroquel does not make this medicine bad for others. I don't wish to make it a hard fact or blanket statement. I don't encourage other users to quit Seroquel cold-turkey)

I'm on Quetiapine 25mg once a day since 6months and I gained 20kgs. My sedentary lifestyle and eating habits were same before and after starting Quetiapine. I gained weight just like that. My question is - will I lose 20kgs just like that after stopping Quetiapine? Because I also have a heart disease (mitral regurgitation) and don't want to exercise as it is a really unpleasant experience for me and as far as diet is concerned, I already eat limited food. Could others please share their experience?🙏🙏
