X-Men #70 (blue team - 1991)
Jean is moving herself and Scott, keeping the nanotechs apart, keeping Scott sedated and performing a Memory Dump on Cecilia.
Later, Jean keeps holding *millions* of microscopic machines with her tk, while keeping Scott telepatically sedated before she finally collapses.
And she can't put Erik to sleep and carry him herself? Puh-lease!
NOTE: Would I have prefer if she hadn't collapsed? Yes! But it was a feat using both her powers under the highest stress you can imagine, because the man in question is her husband.
NOTE 2: I got just some of the panels because she keeps this up for the most part of the issue.
