i was induced & i found the synto contractions crazy as well as having back labour. i had the saline injections first (which were useful & made me declare that i acutally now knew what pain on a scale of 10 was ). they seemed to be turning the synto up ALOT & at one point they had to stop it completely because the contractions were just coming right on top of each other. i asked for gas around then & i found it good. i think it was the idea of focusing on something else other than the contraction that was really good but i did also feel stoned. they only turned it up once & turned it off when i started pushing. i would definitely consider it again.
