Hi,
I have the same problem with feeling like I'm tipping forward. I catch myself also. I have no idea what causes it. It just started happening one day. I also have a problem with getting dizzy if I look up towards the sky. So, I don't. Apparently it's something to do with getting older. I'm just careful all the time and move a little slower so I don't trip. This doesn't happen everyday just periodically. But I never know when. I just pray about it and keep going on with my life. Drinking a lot of water helps a little.
I wish you the best.
