Same:
I had two of the six month Lupron injections, and had most of the side effects/effects that you note. The severity of side effects for myself did not decrease with the second injection. I found the following to be helpful in limiting intensity of the side effects:
1) exercise, although difficult it helped tremendously. I walked daily and also initiated a weightlifting program.
2) Cymbalta, a pain relieving antidepressant helped significantly with hot flashes, mood swings, and situational depression. After completing Lupron I was able to withdraw completely from the drug.
3) Daily naps helped significantly as well.
4) Having a spiritual foundation was helpful. Daily scripture reading was essential for me.
5) continue to stay and engage on this forum. Lots of good useful information and encouragement. Remember the positive effects of using ADT therapy despite the short term hell we have to go through.
6) I think one of my biggest issues was weight gain. Retrospectively, I probably should have limited caloric intake significantly during ADT treatment.
Good luck, hang in there it does get better after completion.
