I found after my hysterectomy that as I wasn't doing much when I did do things I was dizzy & very tired so after this op no matter how fizzy I got to start with I made myself get out & about. Do things so that I could stand for length of time. I half expect to feel even more crap than I usually do after the summer break as I return to work, 9 wks off (sick leave & summer holidays), is a long time & no doubt any lack in my diet will be shown up pretty quickly. I've ordered some trial samples of protein bars in case they are needed to start with & a shake cup to take with me to top up with if needed, & hope I get the balance right quickly so I don't feel to rough.
