Impact after Kidney Donation?

My kin needs a kidney transplantation and I plan to give 1 of my kidneys. Please explain what could be potential impact on my natural way of living, after my kidney donation.

I received a kidney from my aunt in March. She really wanted to do it, and she did very well. She had surgery on Thursday and was out of the hospital 2 days later - Saturday. Up and walking around and going to restaurants and visiting ME in the hospital.
There is a very small risk of death from the surgery itself. I like to think of it as equivalent to a few years worth of normal traveling around in a car. So, you have to think whether the risk is worth it to you. Also, there is some higher risk of lingering pain or other post surgery problems. My aunt is doing fine. Statistically, I don't think they've found any increased likelihood of disease, except maybe a slight tendency toward slightly higher blood pressure.
They do advise you not to take Advil (ibuprofen) or other NSAID medications for pain relief, I believe.
The best website I know for living organ donors is
http://www.livingdonorsonline.org/
Lots of info, and personal stories, and a bulletin board for discussing it all, both good and bad.

Some info from livingdonorsonline:
"These studies and others like them strongly suggest there are few if any consequences from donating a kidney. However, some precautions naturally are in order. For example, you may need to limit or give up activities that could damage your remaining kidney, such as rough contact sports (boxing or American football). Pregnancy for the most part is not a problem following donation, but a female should let the obstetrician know they have only one kidney so kidney function can be monitored.

As noted above, some studies have shown a slightly higher risk of high blood pressure and proteinuria. These risks can be managed and monitored through regular physical exams, blood tests, and urine tests."
