I personally would keep loading for at least 12 to 14 days depending on how your head is feeling. The one a day verses 5/6 is great improvement and very similar to my own experience when starting on the D. I first started getting less hits per day and then the hits that remained here and there were very muted in comparison. I loaded with 100,000 IU/day along with all co-factors for 14/days. This is just what I myself would do and is not necessarily the recommended protocol. Maybe the amazing Batch @xxx will give some advice.
