I haven't eaten that cereal in maybe two months. Maybe longer. So that's perhaps a factor. But can it stay in your system for months like that? Who knows?
Anyway, this is easily solved. Just eat some more of that cereal. That stuff is amazing. I'll have to get it next time I go to the shop. But I just went today so it will be a few days. At least I bought fruit. That should help too. Raspberries.
