There's a facility down the street from me called Celerion. It's the only place in Ireland that I know of.

I took down a few names of places in England from other participants I've spoken with:

HMR
Parexel
Covance
Quotient

It's unlikely I'll ever personally travel over to any of these places since the gaff beside me pays so well that English peeps actually come over to us. But the English doods (and some Irish who could be bothered traveling over) use them.

Feeding patterns are breakfast, lunch, dinner, and a snack for supper. The menu is chosen for you and it's generally not bad. I usually lose at least a few pounds each time I do a trial because there's no access to junk food.

You would have to forget about your specific dieting and eating patterns for the duration of the trial. Which I've always been happy to do for the thousands we get paid.
