I believe 2 wks is normal wait time between. I had 1 block and I was able to steam clean my carpets instead of my husband doing it. Imwas even able to walk around the block with my son. Not everyone responds the same way to the same treatment though. Rsd is a very different beast from most diseases. Its like comparing a dog and a lion. Yeah some can look like lions but there totally different. Be patient and don't stress.
