Mine has bounced around a lot, between 36 and 38, I've been told a temperature of 36 is nothing to worry about, even if im complaining I'm chilled to the bone when it is. Most doctors have found the low grade fever confusing when it pops up and don't know what to do with me!
A comfy 36.9 right now, Im normally 36 and freezing this time of night, keep those B12 injections coming!!
