20mg Feeling dull

Just done two weeks of 20mg and I feel really dull with barely any energy/motivation and pretty annoying tension headaches. It’s not low enough to make me cry but low enough for me to be frustrated with where I am.

I was previously on 20mg and tapered down to 5mg before my symptoms came back so I’ve gone back up.

Does the dullness go away, I never felt like this last time.
