I've been on synthroid for over 24 years and don't worry too much about the 1 hour limitation. Sure, don't eat it and then immediately eat, but just give it some time to start to dissolve before you eat. Maybe get up, take the pill, then have your shower, make lunches, whatever, then eat.
Having said that, I take mine, then make lunches, then eat (about a 20 minute gap) and have never had any issues.
