I love asparagus and honestly, I have never noticed any really foul odors from doing so. I have to wear all the time I *might* fall asleep and frequently need to wear just about all of the time period as I have severe urgency issues but only when I'm not continually leaking (without any sensation whatsoever which is worsening over the past 18-24 mos) and frequently wind up in the same diaper for 12 hours consistently. I grant you that due to the prices of everything I'm not eating asparagus as often as I used to but I still eat it at least a few times per month, especially with meat. I wish I could eat it more as i really and truly enjoy the taste.
One other issue i have may be partially responsible for me not really smelling this. I'm ALWAYS THIRSTY! I drink a minimum of 2 gallons of Crystal Light lemonade (with 8 ounces of pure lemon juice in every gallon, simply tastes AMAZING) being my drink of choice. I also drink at least 2 sizeable cups of coffee every day, or at least every day I'm able to get out of bed which hasn't been going very well for the past couple of weeks sadly. I also eat a pretty big bowl of cereal for breakfast (and sometimes dinner...I happen to LOVE Wheaties & Special K) so figure in at least 12 ounces of 2% milk as well.
I had a kidney function test run by my VA Dr's a month ago and they're astonished as my kidney function is damn near perfect despite the multitude of medical issues I have and the fact I'm weeks away from being 52 as kidney function generally degrades with age and especially with the tons (over $100k/yr) of prescription medications I've been on for most of 20 years. My Dr was pleasantly surprised at this.
Now, I have no idea if this has anything to do with anything or if it is in any way related, but I figured I'd add that information.
