Worry not. Know what you need to do and just go for it. Dr. Miranda is there for whatever support you need. If you don't achieve the desired goal keep your head up. I was 398 and needed to be 362 in about 7 weeks. Didn't look real hopeful the first few weeks but the day before my flight I was at 359. On the day of my surgery, I was at 357. Stress will do you no good.
