Welcome Sydney ! I too had the L5-S1 herniation. I really had no choice but to have the hemilaminectomy because the disc was pushed so far into the Sciatic nerve that NOTHING would even touch the pain. That was on the right side. The surgery was successful in that I no longer have the right side sciatic pain; however, the neurosurgeon that operated on me did not send me to any type of physical therapy afterwards - didn't even mention it - nor exercises. As a result in December 2000 my lower back started hurting and has gotten chronically worse ! I kept going back to him and he would tell me that there was nothing more he could do for me - that I had to lose weight ! Well, I did lose weight and guess what? I AM STILL IN CHRONIC PAIN ! Anyway went to numerous docs, had 2 more MRI's - went to an orthosurgeon who wants to do a fusion. I don't want another surgery. My last resort - Pain Management. I am currently being treated by a wonderful pain management doc. She thinks I will eventually get better, we are just trying different things. The last thing we tried recently was facet block injections (a form of epidural) that were EXTREMELY PAINFUL ! AND DID NOT HELP AT ALL ! On top of my low back pain, my left buttocks and leg now have sciatic pain. The pain management doc feels that (after examination) the periformis muscle is tightening on the sciatic nerve. I am going for another MRI within the next two weeks to make sure nothing is herniated. In the meantime I am taking MS-contin 30 mg 5 x day and hydrocodone (10/325 mg) 2 every 4 hours for pain.
Good luck to you in what ever you decide to do. I do believe that the longer you wait the worse things will be. As far as the outcome of the surgery? WHO KNOWS ! No one can predict that unfortunately. They tell you odds and chances, but the ultimate decision is yours. Keep on researching - get as much info as you can and then make your decision.

Hang in there !
