Flip turns

When I swam in high school I never had any instruction from a coach. Our coach's philosophy was if you wanted better times you had to swim faster. Technique was never mentioned. I just got back into swimming last year and have talked to several swmmers at the club I workout at. One mentioned USMS which brought me here. I have read several of the training articles and have applied some of them to my workouts. My times have improved but I still have a long way to go. My concern now is flip turns. I have been doing open turns and log a time of around 37 minutes for 2000 meters. I know I can dramatically improve that time if I did flip turns but my flip turns leave be gasping for air. I turn head down at the wall and use arms and legs to ball up and create the turn all the while exhaling every bit of air in my lungs. I exhale to that degree to keep water out of my nose as I have a slight allergy to chlorine and it leaves my nose burning if water gets in. When I complete the turn it leaves me exhausted and I can't keep the pace I do when I use open turns. I know there has to be a better way to do a flip turn where I won't be gasping for air when I complete it. Does anyone know of a website or book or something that analyzes the flip turn so I can rid myself of this problem? Thanks, Julie
