He was referring to taking the LSD as the MDMA was wearing off.

What did he mean by "post-MDMA"? The day after? Or when the MDMA was wearing off?
I wouldn't be so keen take Shulgins work as law - taking LSD at the end of a heavy MDMA session when you're already exhausted - meaning you're going to be awake for another 12-24 hours sounds like a waste of LSD to me. Not great for your health either.
Any idea why he was only taking 65ug? That's not really a psychedelic dose anyway - was he taking that because he knew LSD didn't become psychedelic after MDMA no matter what dose he took?

I personally prefer to take LSD first, MDMA one hour later...but I have done it the other way around and what you say just was not my experience. MDMA never particularly makes me exhausted anyway (beyond having stayed up all night), but taking a psychedelic on the tail end (LSD numerous times, 2C-I on one occasion, and 2C-T-7 a couple or three times in my case) is very enjoyable and not at all 'rough' or a producer of a more severe hangover.
