hi jigboy, i too had humana. but,,,,the 6 mo. diet thing is just a doc. preferabblly your pc, typing a letter saying that u have tried in the last 6 months different diets but to no avail. tell him u tried, atkins, wt. watcher, tops, nutrisystem etc. or watever u tried and did loose a little but gained it back. all u need is a letter stating this from a doctor. humana approved me within a week. fill out ur paper work the wt. loss dr. sends you and your support letter 'thats what it is called from ur personal doc.' and all the paper work. you should not have a problem. you dont have to 'PROVE' you were on these diets. just give an approximate date of when u did try them. you do need to have a bmi of over 40 or a comorbitie such as diabetes, high blood pressure or be over a 100 pounds overwt. if i can help u more, my email addy is 'chubgirl2003@yahoo.com. humana has their own bariatric program now too
