Are you a delayed dumper?

I am becoming one more and more often. You might think this could be a good thing, you imagine that you could go to a party, restaurant, or event and eat something questionable and not have to worry about dumping until you are safely home. Yeah, nice theory except it doesn't always work that way. In fact, it just ads more of a feeling of gambling to it all. I pass the spread at yet another break room potluck and see a arrangement of cheesecake bites. Oh, I want one! Then the voice in my head (okay it's not really my voice, it comes out more like Clint Eastwood's voice), says, "Are you feeling lucky? Are you?". I know that worst case scenario, I can eat one and dump immediately at work and maybe besides the horrible embarrassment of being in the bathroom (which shares a very thin wall with the break room by the way) dumping for goodness knows how long, I may become ill enough that I have to go home early and have to explain (if the gas and the uncontrollable clutching my my lower abdomen due to the cramps don't give me away) why so everyone can think to themselves, "Why was she hanging around the potluck table anyway? Didn't she have weight loss surgery? I thought they weren't able to eat x,y,z after that! No wonder she is sick!" I could just have the sweats and heart palpitations and become really tired. Best case scenario (and still not great), I could be fine till I get home and have it happen and be unable to get to sleep because of the cramps and my husband wouldn't be able to sleep because of my gas! I could wake with it in the middle of the night and while baby gate hurdling is bad enough during the day, it is down right dangerous when half asleep!
Last night I was bad, I lapsed. I had a dove bar. It only had 15 grms of sugar which is sometimes acceptable for me (again a gamble) and I was fine..till this morning. I was feeding Lilith her breakfast when all of a sudden I started to have horrible cramps (I have noticed that the delayed dump is usually very painful), I jump up after throwing a handful of Cheerios on her tray and head for the bathroom. (before you start thinking what a bad mother I am, Lilith sits in a booster seat that she is able to get in and out of unassisted so I knew she would be okay besides she was enthralled by her morning ritual of Sesame Street). It was quick and awful and since I hadn't eaten anything yet, I knew it had to be the Dove bar from last night. I wonder how common this becomes the further you get from surgery. Maybe it is a cumulative effect, the bite that broke the dumping barrier so to speak. You can get away with one item containing a questionable amount of sugar, fat, or carbs but if you have another...even later in the day, it will cause you to dump later on. I am sensitive to dairy and husband accidentally purchased 1% instead of fat free milk and I had a low carb Chai before bed and I wonder if that might not have been too much in addition to the Dove bar?
I don't know but I am not going to plan any trips to Vegas anytime soon because anyway you look at it, you almost always loose the gamble when it comes to cheating (either you dump, you gain, or you just feel bad that you did it) after wls. No Clint, I don't feel lucky I think as I walk past the Cheesecake bites and to the staff fridge to get my fat free cottage cheese.
