I have recently started following the spiritual pathway and have begun practicing the per-requisites to meditation. It has been about a week since I started to practice mindfulness and vigilance in my daily activities and before going to bed I engage in a meditation session involving 10 minutes of concentrating on my breath followed by chanting of a mantra for 10-15 mins (either IN.EN.ON.UN.AN or Gate Gate Pargate parsamgate bodhi svaha). Then I self-reflect over the actions of my day and sometimes read a spiritual topic book and then go to sleep. In the morning I wake up and perform 1 minutes of Wim Hof breathing
and 10 minutes of Qi Gong exercises
I am sleeping about 8 hours a day since I began meditation (1.5-2 hours longer than the number of hours I usually slept). Yet, from the past 2-3 days when I wake up in the morning I feel listless, lethargic and experience a lot of gas and headaches. I have suffered from migraines since I was a child so I usually take precautions with eating items which will not trigger a migraine.
Am I doing something wrong or improperly because of which I am feeling so tired and getting migraines? I wanted to seek some guidance on my situation.
Thank you for your help.
