sophie- hope you're feeling better! i know how you feel, even 10
pounds can make you sluggish. and effects stamina.
i have been exercising since I was 8 years old.. jane fonda was my first video

and have sometimes been chubby around 150 to 160.. but have never weighed this much. my work has kept me focused away from exercise and proper
nutrition.
you have the right idea by catching yourself in "the early stages". i promised myself that massive
weight gain will never happen to me again- and it won't- thanks to Ron Brown's advice of daily measurements.
