I've been having the same problem as well. Never noticed it this pronounced before. Was talking to my wife about it, she's been feeling it as well... we both smoke the same stuff, so not surprising.
However we then both talked to people in our offices, they are not smokers, and are all experiencing higher anxiety these days. Some at my wife's office were postulating that all the crazyness going on these days climate change, brexit, trump you name it, has people at a higher than usual level of anxiety.
As a huge sative fan myself... I think we are entering an indica future.
