Help with package

Hello, 

I have almost finished a companion mod for Morroblivion but i want to fix the last details. I need help from anyone who knows becaus ei m stuck like 2 days....

We most know how drink package work. We get UseItemAt and apply a potion. The animation gives the actor to stand and drink. If we set a specific ref of a chair he may sit and drink too.

This is my problem. I created companions that act by themselves, using packages of current location. I made them search in current location for furniture and sit. This makes them select random chairs.

I want them to sit and drink while they are sitting. This is not easy to be done but i m trying.

I thought that it may be done the way the eat package works. At eat package the actor will sit down in a random chair (if it is not specified) and eat automatically. Can this be done with UseItemAt (drink) package too? 

This is how i done it so far but it is not working properly. The followind script is for reading but its the same thing. The actor sits and when the read package starts he stands up to read.
