As you probably know, when taking a string of lessons, it's expected that your swing will be worse before getting better. That time period depends on how much you practice correctly and how often. With that being said, if your swing right now is a huge mix of many different ideas, going to another instructor won't "cure" you right away. Might take another month or so of high scores before you get another swing down.If your current instructor doesn't give drills, try remembering what he works on with you during lessons and try to recreate it in front of mirrors/video cameras.
