Snap!
I changed to Quetiapine almost a year ago and had outrageous sugar cravings. As a result, I put on two stones really rapidly, and then a third one crept on after that. I went from 7.5stones to 10.5stones which is far too heavy for my 5ft 1" frame.
I absolutely understand what you say about over eating and not exercising because of the depression. It is so bloody hard sometimes just to get out of bed. I used to see lots of school Mums heading off for a run after drop off time and almost cry because there was no way I was going to be able to do that.
I am really well now and pretty much coping with day to day stuff and just after New Year, I decided enough was enough. I have accepted that I can't do moderation with anything, so instead of kidding myself that I could have one biscuit and put the rest back in the cupboard, I decided to try cold turkey on refined sugar. So, none of the obvious stuff - cakes, biscuits, sweets, chocolate and the like, but also looking at labels for added sugar. You would be surprised how much sugar there is in cereal and the like! No more than two pieces of fruit a day, but not going hungry, just making different choices. Not cutting carbs either, but certainly eating fewer of them. I have low carbed before, but I have always cracked and scoffed unsuitable stuff then given up.
The first couple of days were hard, I had very real withdrawal symptoms, but it has become easier. I have done almost 3 weeks and have lost 6kgs (almost a stone).
But, aside from the weight loss, I have found that I am nowhere near as sluggish and have a good deal more energy. The Quetiapine wipes me out, and the mornings were really hard, but now I honestly don't feel so bad in the mornings and I don't get the wild highs and lows that too much sugar causes.
This may all sound difficult to you, certainly if you had told me to do this a few months ago I would have said that I couldn't. I felt really out of control of the situation. Every time I felt my fat wobble, or I couldn't do up my jeans, I got angry that the overeating, caused by the medication, necessary because of my illness had made me fat. I think this is because it reminded me that I had this illness that I didn't ask for!! Somehow, I reached the point where I decided that I was no longer going to let the illness/medication/overeating situation get the better of me and here I am.
