You know those days you just feel off, no strenght what so ever. I felt the last couple of days, a bit sick tired etc. So I digged out a this Green Juice recipe, just to get me back on the feet and not taste to bad and hey they gave a version if you dont have a juice machine. 
So now of to the Supermarket and get some vegetables and fruits.

Makes: 2 servings, about 8 ounces each
Active Time: 15 minutes
Total Time: 15 minutes
(Note: Each recipe makes two 8- to 10-ounce servings of juice.)
1/2 cup fresh parsley
3 cups spinach
1/2 lemon, peeled
2 medium pears, cut into eighths
6 large stalks celery, trimmed
Ice cubes (optional)
Working in this order, process parsley, spinach, lemon, pears and celery through a juicer according to the manufacturer’s directions.
Fill 2 glasses with ice, if desired, and pour the juice into the glasses. Serve immediately.
Without a juicer:
Coarsely chop all ingredients.
1) Place the soft and/or juice ingredients in the blender and process until liquefied
2) Add the remaining ingredients; blend until liquefied.
3) Cut two 24-inch-long pieces of cheesecloth. Completely unfold each piece and then stack the pieces on top of each other.
4) Fold the double stack in half so you have a 4-layer stack of cloth.
5) Line a large bowl with the cheesecloth and pour the contents of the blender into the center. 6) Gather the edges of the cloth together in one hand and use the other hand to twist and squeeze the bundle to extract all the juice from the pulp.
