If someone tells you, you look sick, you can still lose another 5 pounds. When i reach the point of being a little dizzy or light headed i rest for a few days until all is well. Then i resume my riding. If i get up off the sofa to fast and get dizzy same thing. You can lose a lot of water weight and gain it right back. You may have reached a plateau and will take some time before more weight loss. Just keep recording you daily weight and a pattern will develop.
