Lupron shot....how long before i am back to my "self"?

I am 42 and have been receiving Lupron shots for 5 months due to stage 4 endometriosis. I don't want to have a hysterectomy so my doctor said this was a way to possible avoid surgery. Anyhow, I am scheduled for my last shot at the end of July. I have had horrible hot flashes and night sweats.....luckily no mood swings or lack of sex drive. I only had one episode of pain which turned out to be from a cyst on my ovary. When they went in laproscopic to remove cyst they found out that i had stage 4 endo. I never had any pain associated with the endometriosis. My question is, after I get my last Lupron shot...July 28th...how long before my body returns to normal i.e. no hot flashes or night sweats? I had an IUD put in 4 months prior to finding out I had endometriosis. So assume I won't have my periods...(yeah!!!) Anybody who has went through this, i would greatly appreciate if you could let me know how long it took for you!! Thanks!!
