I have a desktop that runs Windows 11. The C drive has 219 GB. I have an additional D drive for more storage (931 GB). I noticed in the past few months that my C drive was almost entirely full. On April 28, I had 4.51 GB free. So I took almost all of my saved files and moved them to the D drive. That freed up about 9 GB, so that my C drive had 13.8 GB free on April 29. Almost immediately, my C drive filled back up. Today, I'm down to 611 MB left.

WHAT IS HAPPENING? Why is it filling up so fast? I have a malware protection software that's constantly running and it didn't find any viruses. Only about 110 GB of the 219 is "installed apps." The rest is "System & Reserved" and "Other." Why does Windows need so much space to run? I don't know what I can safely delete and not break things.

I don't want advice on how to make more space, I want to know WHY it's filling up so fast. It seems like any time I make more space, it immediately fills back up, like a boat with a leak. I want to stop the leak. How can I find out what it filling up my hard drive?

I play tennis. In the past I've used the finger-prick manual blood check and noticed that playing tennis raises my glucose levels, or at least doesn't make it go down like you would expect. I got a CGM recently and so now that the outdoor tennis season has started I've been able to monitor my glucose level during a match. When I played doubles, it went down, but when I played singles, where I run a lot harder, it has shot up.

This past Saturday I played a really tough 3-set battle. We played for over two hours and my whole body hurt afterwards. (This is normal, I'm in my 50's.) But I was looking at my glucose during the match, and about an hour in, it shot up to over 200 and stayed there for the rest of the match. (Before that, I hadn't been over 200 the whole time I've been wearing the CGM.) I kinda wish I didn't see it because I was freaking out and it made me want to just finish the match quicker so I could bring my glucose level down. It was my first really hard workout of the year, and I wonder if this was just because I'm not in shape yet?

As soon as I finished playing, it started to come down, and dropped all the way down the 64 an hour later (which is SUPER LOW for me, maybe even a record low.) Then it bounced back up to a more "normal" level for me.

Anyway, any other T2 diabetics have this issue? Does your glucose shoot way up when you work out? I've read that having it shoot up and then come down is worse for you than just having it more level throughout the day. Any insights or advice? I'm not going to stop playing tennis, because I know it's good for me in a lot of other ways.
