I have posted a couple of times trying to get someone to help me understand why I was experiencing extreme sedation with things that should have no such effect. The effect was so strong that it would alarm me so that I would struggle out of a deep sleep. I marked it down as akin to the Night Terrors but was still uneasy. At various times I had experienced it with magnesium, B-12, and a couple of others.

Then yesterday I came across an E-health survey that said that a very rare side effect of the beta blocker prandoprolol (sp) was "acute respiratory collapse" as in "dead"! So, do pass that tomato, soccertese, old chap.
