Have you tried vaping? It is usually less irritating than smoking. I have an asthmatic friend who coughs and chokes when she tokes. She vapes just fine, however.

And try a bedtime snack of an edible! My hubby suffers from pain and a "magic muffin" in the evening makes his mornings much better. Since eating has a much longer effect time, it might lessen the morning nausea.

I remember my morning sickness! Waking up sick to your stomach really sucks! And incidentally, my morning sickness was lessened by a large dose of B-6 just before bed. I'd still feel somewhat nauseous when I got up, but I wouldn't actually vomit. A small improvement. Pot was better, but not always available.
