@indigo Follow-up. It turns out they finally did make a diagnosis on my friend: progressive supranuclear palsy. I hadn't talked to them about the disease in a few months so hadn't heard they'd found out. I mostly just see my friend and she can't talk well enough to tell me this sort of thing. We had smoothies again today. It was pleasant. I hadn't had a smoothie in years and now I'm having them all the time. I've tried all kinds of varieties and we've mostly decided we like blueberry the best as the primary fruit. I usually get them made with apple juice but we've decided to try coconut milk next week. Not sure I'm really down for that my friend seemed happy with that idea. :-)
