Answer 1

It's a bit long winded but you could do

static id ObjectOrNull(id object)
{
  return object ?: [NSNull null];
}

parameters:@{
  @"auth_token"         : ObjectOrNull(token),
  @"name"               : ObjectOrNull(drunk.name),
  @"date_started"       : ObjectOrNull(drunk.started_drinking),
  @"date_stopped"       : ObjectOrNull(drunk.stopped_drinking),
  @"prescribing_doctor" : ObjectOrNull(drunk.fat),
  @"pharmacy"           : ObjectOrNull(drunk.dumb),
}
