This was to say the least a puzzling show. Especially when Sam is puzzled. But i8t had it's moments. Every one starts getting tired and irratable from lack of sleep and the knowledge that there will be no sleep until they figure this thing out.
Vala on the other hand had her own adventure going on back at the sgc.
She really wants to do this and they are really putting her through it. When Woolsy confronts her and offers to have her passed if she would just agree to provide information to the nid about what they find and what goes on at the sgc.
After they realize that the stimulants that are taking to stay awake are getting to the harmfukl level they decide that they can no longer take anymore of them and they have to stay awake the old fashioned way. Sam and Daniel are left at the base and are slowly but surely running out of juice. Just in time for the hazmat team to come in just in time to save them. There was a lot going on in this episode, but it was realy good and had a great ending. I liked it much.
