If a missed dose is caught in time to allow a snack without going over your DCI. You can take a dose wait 30 minutes and then have a snack that includes protein & veggies. If your calories for the day do not allow this then just return to your normal dosing schedule at the next meal. If you have regular eating times it would be a good idea to set an alarm to assist you in the 30 minute reminder to take your dose.
