Orange Juice and Wheatgrass

Its now day 3, and I'm starting to enjoy the experience.
Yesterday's menu was as follows:

• wheat grass shot (yuck)
  
• orange juice (5 oranges)
  
• celery juice with spinach, carrot, and apple
• orange juice (5 oranges)
  

Today's menu:

• wheat grass shot (still yuck!)
• orange juice (with 1/2 lemon)
  
• celery, carrot and apple
• orange juice
• orange juice
  

At the end of day 1 I felt really tired and had an early night, but last night I felt fine. I've been able to stay pretty active, and apart from a bad metallic taste in my mouth I'm good.
