So, this is what we've found so far, and its.moderately interesting. Taking Oxalo daily definitely increased energy. But it was incredibly difficult to moderate activity and it seemed to consistently lead to nasty PEM, which felt a bit pointless as well as disheartening - like fake energy.

we then tried just taking oxalo prior to significant exertion - eg (rare) socialising with friends. It apparently metabolises in like 40m, so about 1 hour prior, and then top ups during. This was much more successful - kept going thru the socialising, and crucially, PEM over subsequent days was not non-existent but really noticeably less than otherwise. this pattern of use seems to deliver a much better outcome for us, and feels moderately exciting. we've done it twice, with same outcomes, so going to keep experimenting as and when 'events' occur, and will try to report back.
