How to remove FastMM497 from my project file?

Question

After spending a week of my time running using FastMM on my project file, I now have completely gone through my program and to best of my knowledge remove all but 3 error messages raised by FastMM497. Now, I want to remove FastMM from my program and run without it. Can I do that? If I remove it and run my program, will my program start leaking memory? To best of my knowledge I have removed and changed my project option setting back to the way it was before.

However, I did notice that my program is a lot bigger in when I run the executable file. Originally, my program used to be around 5,000KB to 6,000KB when it starts up. After working through FastMM, now it is around 21,000KB in the Task Manager. Am I looking at this correctly?

Can I just leave FastMM497 in my program and deploy it as is to my users?
