In the simplest of terms, a drug's volume of distribution is that volume of bodily fluid into which a drug dose is dissolved. Therefore, if we know the dose that was given, and we can measure the serum level (concentration), then we can calculate a volume: Volume of distribution = Dose / drug concentration.
As soon as you can make the reservation, do it, but the general consensus is at least three to six months in advance of the date. By three months out, couples have a good idea how many guests will be attending and they can plan a menu that doesnât conflict with their wedding day.
For a Sunday or holiday wedding, you have more options. Since the rehearsal dinner has become more of a celebration in its own right than just a formality, some couples are holding the event two nights prior to the wedding. This way, there's more time to relax, recuperate, and get ready for the main event.
