I'm a bit confused as how going with a 1" longer draw length helped your problem??, but to address your peep issue:

1. Try a bigger peep. 2. you didn't say what type of release you use, but if you have an adjustable caliper release, try shortening thatto bring the peep closer to you, but you'll haveto adjustyour anchor point. 3. If you use a loop, shorten that up as well or as a last resort, you could shoot off the string.
