I have to preface this post with this: I hate Detrol, Ditropan and all the anticholonergics because of the dizzy, make you constipated, cottonmouth thing. That being said, I think if your bladder, in isolation, was your only problem, then I think they would be wonderful. However, in interaction with the problems that come with MS, I think it flat screws us up. So you know that I have a bad feeling about those products, but I'm sure not everyone feels that way about them. When I cath at night, I always look for the cloudiness by capturing it and then putting it in an old clear beer mug I have. The reason I think it's important to do everyday, is that if you catch it cloudy and take action quickly, you can clear it up in very short order. However, if you let it set in, it can get dug in. I had my first one about a month after I started and I noticed it right away, got to the doctor that day and was RX'd Cipro, and had clear pee by the next day.
The clean procedure is very important. Not only do you have to sterilize your hands, you really need to sterilize your junk by your urethra just as well as you do your hands. I even reuse my caths for about 3 weeks. Arti thinks I'm nuts for doing that, but that's what my brochure said I could do. I Completely wash them out with antibacterial soap and let them air dry. Then I take them right before use and completely rub them down with Isopropyl. Knock on wood, I haven't had one since and I've been doing it for months since that first one. Also drink at least 8 oz. of Cranberry EVERY day. It won't help if you've already got an infection, but apparently it's good PM.
I really can't help with the other stuff, but if I woke feeling like shit the day after taking a Detrol, I'd blame it on the Detrol, but Marie is right, if you have an infection, you need to knock that down before anything else.
