Excited to continue losing

Options
Well I have been on Phentermine since 9/30/2013. On 10/21/13 I went for a check up on the meds and to get a refill and in that 3 weeks period I had lost 10 lbs. Which is pretty amazing since I had been staring at 255 for the last 2 years it seems. To be down to 245 is a new beginning. I also met with a Nutrition Specialist yesterday 10/24/13 and I was already down to 244; she gave me a generalized plan to stick with but something that can be gradual and not cold turkey on everything which is a plus. The only struggle I have always had is pre-planning meals and snacks. So in a month I have some goals that she will check to see how I am doing. One is eating every 3 hours, walking 20 minutes a day, keeping a food log, and lastly adding 2 veggies per day...should be easy?! Well it helps that if I do not meet these goals I will not be reimbursed by my insurance, haha. Oh and I am eating only 1200 calories a day.
