That's a good question. There would be other items that would be depleated, but at what rate is hard to tell. My thoughts are that your normal schedule may have set you up good for a small lapse. After 6 weeks you may have not noticed, but things may be on the decline..........
If you want to back off, I think I would go from biweekly to monthly for a while and see if you notice a change, rather than going to a further extreme.
