I was down to 130 for a while after dropping from 245 in a matter of weeks, three years ago. I went up to 170, which took over a year to gain, but then dropped to 140 from another treatment in 2011, but built up to 180, and then lost 10 pounds to 170 from another treatment, which ended in 11/12 I built myself up to 190 right now!
Try adding vegatble oil, vegetable oil, etc. to any drinks, foods, which add extra calories, taste, and fat increases appetite too. To eat foods more easily, you can spray them with an pump oil mister. I have brand called "Misto" that is a spray pump, which you can spray on food.
Good luck.
