It is probably not a good idea to break it in segments like this...you take the risk of loosing potency in killing the parasites in your body...and from what it sounds like you may not want to do that.....
My husband worked all the way through his cleanse and depending on your body you may be able to make it through your whole cleanse and still be able to do what you need to do...You may just be more tired....just be sure to drink lots and lots and lots of water, or consider getting the tea to help keep you on your A game while you are doing your project....Prayers to you!
