Morning glory seed gave me a mild LSD like trip with catatonia. (around 100-200 seeds)
All the reports I read about "sedative" effects are a bit strange to me. Maybe just a stab at describing something.
I never got sleepy, I just somehow did not feel like moving, at all, for hours, no matter the position I started in.
To me, it felt like a description of the symptoms of catatonic schizophrenia (this was decades ago). The patients would sit in the same, often appearing uncomfortable, position for large portions of the day.
I was a teenager, just discovering LSD, who had move to a new area with no connections. I did the LSA seeds 10 or so times until I finally was able to obtain LSD.
The high was not real strong but plenty pleasant enough except for the "catatonia". I remember my first time finally getting some LSD that it felt a bit "jangly" and stimulating.
Woodrose was the same, but with much more of the catatonic effect. I sat on my door stoop one time, in the same position, for hours watching the cars go by. (about 8 seeds)
I was pleasantly and mildly tripping and thought nothing of how I appeared to the rubes. Some neighbor kids stopped by and talked to me and I conversed with them lucidly... but stayed in that same position I had been in for hours.
Some years later, when they were partying too, they told me how they stopped by and talked "when I was wasted" that time.
I didn't understand, I wasn't super buzzed. I just didn't want to move and what's the problem with that?
They did confirm that I seemed lucid to converse with, just hadn't moved for 3-4 hours.
And, yes, that effect is a deal breaker.
