C30 is not a good idea.

Do you think C30 is causing the sag? I think that might slow down Q2,
but the sag is caused by having to charge C31. What kind of 3.6V battery
is that?

Hint to the OP: If you can, set your scope's trigger delay to -1 units
so we can see what things looked like before they fell off the edge of
the earth.
