Home retreat advice/precautions?

[Itsokimok]

I'm off work for  a month and a half and wanted to make use of the rare opportunity by doing a retreat at home. I want to do meditation, Neti Neti and self-inquiry for 2 weeks. I can sit for a long time but have never done something this intense. Should I do half days or shoot for full days for the whole 2 weeks? Also should I stick with one method for one day and another one the next day or do all of them each day? 

Thanks!
