I also stopped when my stomach started looking a little bloated. I later learned that most bulks are 1-3 months, not 4-6 months like I did. I really enjoyed the first three months and the back half got monotonous and I hated needing to eat extra to keep from feeling hungry in the middle of the night.
I tracked calories with no adjustments for a week to see how much I actually needed to feel full, which was 1800-2000 at first and slid down to maintenance. I lost weight at roughly 1 lb a month for a good 6-8 months.
