If you have pierced your tongue, and if you are unable to eat, I have want to give suggestion or advice about it. You need to stay away from dairy and beer and cigarettes for about 5 days even if you feel fine, because they can cause a nasty yeast infection in your mouth called thrush. When I got my tongue pierced, I stuck to soft foods for about 2 days, and was eating normal foods but no dairy by the third day. Within a week you should be fine. Definitely switch to a shorter barbell as soon as you possibly can - it will make it much easier to talk and eat. I have a terrible lisp with a 5/8" barbell so I got a shorter one, and I'm very comfortable at 1/2"
