ilovecherries Well done for not succumbing to the bread.
After a whoosh I tend to stick or even creep up a little for a few days and then drop a little.
STS isn't a bad thing after a whoosh, I look at it as a storage issue, body whooshes out the water only fat cells, then moves the half fat ones to make all fat ones, but tops the empties with water. Then over the next little while goes Bollocks to carrying this cell of water and evaporates it out in smelly breath. don't know it that is true but by the time I beginning to doubt myself the scale has moved to a new number and I back feeling good.

Soon that's going to be a great NSV. When you get to the halfway point up the hill and then to the top. Remember to change gears early as to not screw the cog and overstretch the chain.
Lucky you having the shower, I have to use the single occupant toilet sink for the submariner wash.
Also if you are going to ride everyday get yourself fitted on the bike properly. Saves a lot of pain, I used a website that told me different things to measure on the body, i.e leg, torso arm length etc to properly size the bike to me. felt strange first ride or 3 but now is so easy on the knees and back.
