I understood it this way - the 5mg daily dose is to keep a stable level in your system, so if you want to take 20mg, you need to NOT do that on top of a daily 5mg.
Again, from my uro, if not using the 5mg daily, I could take 2, 3, or 4 of the 5mg at one time to get to the 10, 15, or 20 dose.
It just depends on the context you are taking them in.
F8 - exactly.
The uro wants no more than 40mg total per week for me, and warned not to do 20mg two days in a row - I did try that (only once), but the low back pain was a real killer, and left me unable to get out of bed for the pain.
