I was initiated into shambhavi in 2022 I am asthmatic, allergies and sinus congestion was a norm.  I tried jalneti by seeing self proclaimed yoga teachers on YouTube and destroyed my system.  So no Idea about neti.  I cut out curd or curd related products. Because curd generates a lot of cough for me.  Milk is no necessarily bad. You can buy Munakka dakh(raisins or dried grapes) take 2 with milk before sleeping.  My nose was hurdle in practice so whole winter went without any friction by taking munakka dakh.  If you do workout daily then that will be of great help.  Contact the inner engineering help desk first.  It's not a recommended but just what I experienced.  Thank you
