Having a significant other is great for many obvious reasons, but they are particularly useful when it comes to control over your mischievous urges.
Let me set this up for you: you just had a wonderful, small piece of a safe brand of pizza (if you're lucky enough to be at a place in your life where you can handle pizza), and you suddenly feel completely and utterly miserable. You're super bloated and might even be experiencing some urgency. You say, "Baby, don't let me eat a single thing for the rest of the night. Water only."
Now, fast forward a couple of hours. The bloating has dissipated and you're no longer having urgency; the threat of an episode is no more. You open up the pantry and see a snack that you really want, so you grab it and head out to the couch. Your significant other says, "Whoa whoa whoa. You said you couldn't eat anything else all night." You respond with, "Well, yeah, but I feel fine now!" They say, "Put it back."
Grrrr. But goodness how helpful that is! Because you just know that you'd be down for the count if you would have actually eaten the snack. So don't forget to ask your boo to help you stick to your guns and keep your stomach happier than it would have been if you had given into your urge to snack after an almost-episode. It might almost help them feel like they have some control over the thing that has indirectly changed their life too.
