Insomnia can be mild or really horrible. We would look at the basics of the problem as excess or deficient. If stress is the main issue (or even eating late at night- don’t forget that) the its an excess. You might look towards formulas like Jia Wei Xiao Yao Wan. If its anxiety then you might look towards Tian Wan Bu Xin Dan. Insomnia that is “empty”, not stressing but just lying there then look towards Gui Pi Tang.
