Say goodbye to the 150s forever. Good job! Slow and steady wins the race. I don't think you are in danger of plateau. If you are concerned about it-- mix it up a bit. Eat more, eat less, slash grain consumption, change your exercise routine. Don't fret about the water fluctuations. Limit sodium that helps you store water. Drink plenty of fluids, especially water, but remember it all counts, coffee, tea, etc.
