My results are too preliminary to get excited yet, but at least for my short trial, the smaller amount seems to help. Interestingly, my overall sleep doesn't change much, but I do notice more dreams, and Zeo confirms that my REM sleep is up quite a bit.
Here's the raw data (dumped straight from the R software I use to track everything). The one marked in red below is the most interesting number:
I tried potato starch on 91 days, and I have Zeo sleep data for a total of 45 of those days.
On 19 days I took exactly one tablespoon. On 6 days I took more than 0 but less than 1 tablespoon.
For total sleep (Z):
- P-value on days when I had any potato starch: 0.3109656
- P-value on days when I had exactly 1 TBS: 0.2020084
- P-value on days when I had more than 0 but less than 1 TBS: 0.3041962
- P-value on days when I had any potato starch: 0.2505854
- P-value on days when I had exactly 1 TBS: 0.0603005
- P-value on days when I had more than 0 but less than 1 TBS: 0.0012399
- P-value on days when I had any potato starch: 0.5148044
- P-value on days when I had exactly 1 TBS: 0.7402774
- P-value on days when I had more than 0 but less than 1 TBS: 0.3264305
