Endometriomas symptoms and conditions

Hi: My doctor has suggested me lupron depot 3.75mg for three months before doing supracervical laparoscopy. I did ask the doctor about the side effects and she said that you might get hot flashes and mood swings. Thats all she said about the side effects. My first shot is on Tuesday April 15/08. After reading all these experiences i am so scared to take them and planning to talk to the doctor again and looking into the abdominal hystrectomy instead of supracervical laparoscopy. Do you guys think that because it is 3.75mg and not 7 or more mg it might not have that many side effects.
God, I am so confused now, please help me out here.

In brief, I am a 35 year old mother of two. I have been suffering with endo since I am 14. I had a span of 4 years with no symptoms at all and in Sept. 05 I had a total hysterectomy for endo and cancer cells on my cervix. I recently spent a week in the hospital for 2 endometriomas which are on the one and only ovary I have left, they are both bleeding and my doctor whom I trusted and his colleagues recommended a 6 month depo-lupron injection treatment before they do surgery to fix up the endo, they are reluctant to remove the remaining ovary due to my age but I will INSIST until someone listens. They did not tell my husband or I about any side affects and because I was in a tremendous amount of pain and because I trusted Dr. Shine so much I accepted the treatment, they faxed my husband the prescription at his work and he had to go find it when he did finally found it he brought it to St. Marys hospital and the nurse injected me and 2 days later I went home, I was sent home with celebrex, iron pills and morpheine pills for the pain...well I was back in the ER 3 days later because the pain was unbearable, my blood pressure was high and I was going insane, I met with the gyno on call and she expressed her disgust with her colleague for not telling me about the side affects of lupron and how the drug worked. My first shot was on the 13th of April and today is the first day I am feeling human, I have little endo pain but let me tell you the hip and back pain are killing me slowly. I am a very active mother and wife and I play sports but even the thought of that now hurts. I have not been able to work and will not return until I feel good, I am REALLY scared of getting the next injection which will be on the 11th of may and my new doctor told me to go through with the treatment for the next 5 shots because even though it will not be easy she insists that it will help me and once I am done they will perform surgery, I have set-up 2 other appointments with specialists and my Family Doctor is the only one that has been there for me, he follows me daily and has set-up a bone density test. Is there anyone with similiar situation that can help me out. I have other side affects but the hip and back pain are the ones I will never forget, I think I would have 10 more births drug free then to have to experience the pain again after the next shot...
