Glad you managed to take it...

I've talked to my pharmacist about this stuff before, and they say if you're more than 12 or so hours off of taking a pill then to just wait until you take it again (if you take it on a daily basis in the morning as an example).

Won't do you too much harm to miss a dosage, but sometimes your body doesn't much like it (but better than an overdose I'd say!)
