Sleepless nights

Okay so the restless nights have started early this time. I haven't started any meds yet, but I am already not sleeping at night in antisipation for what may be the final outcome. This is the second night of tossing and turning and the thinking what if..... I do not like this part of everything, and this time I am starting it early. I don't know if anyon else has these problems when they are getting ready to go through an IVF/FET cycle, but I have it every time and don't know how to get my mind off it especially when I am trying to sleep.
