It was the only major variable that changed. My wife and I got a CSA and started eating a lot more veggies. The collards though just seemed like they had the most benefit. My suggestion is to use bacon fat as you make them. Make them as tasty as you can (brown sugar, onions, bacon fat...bacon itself gets soggy)....it won't effect the outcome.
Of course this is 100% anecdotal evidence, but it really can't hurt to try! I feel for you though, it really really blows, and the steroids come with their own problems. I've named my permanent floater buddies caused by the steroids Lenny and Squiggy.
