Same. Like a lot of #ActuallyAutistic people, I don't sleep well, and #CBD shortly before bed helps. In fact, I started taking CBD soon after it became legal here, some years before I knew I was autistic.
I now use oil rather than capsules, because oil gives me finer control over the dose and it works out cheaper than other formats. You do have to be careful not to spill it on your top, though: it stains.
I've used #GinkgoBiloba for several decades. It sharpens both my reactions and my cognition.
I take #curcumin for other reasons, but I find it improves my working memory and my digestion as well. Simple turmeric is poorly absorbed and often contaminated with lead, so anyone wanting to experiment with it would be well advised to use a modern, safer, more bioavailable preparation.
