Lupron can really knock us for a loop!
Your side effects are similar to mine. I've really felt the fatigue issues and fight them with frequent breaks, vitamin b-12 complex (I had to titrate this because a little too much gave me the shakes). When working I use a paper towel or wash cloth inside my hat to soak up the sweat - change it often. And I"m not reluctant to ask for help! I"m now off the shots for about 9 months. Everything is coming back but seems soooo slowly. The big deal is my cancer is put to sleep.
So keep fighting every way you can - good diet, exercise as tolerated, reach out to friends for joy, pester your doctors for help, stay tuned here.
May your combined struggle give you blessed relief from a much worse fate.
