Drowsiness is a problem

Hi,
My name is Chandrasekar. I am currently in Taiwan for a process migration and will be returning back to India shortly. I was doinig Sambhavi Maha Mudra for about 3 months and I am now not been able to be very regular nowadays.
My job requires me to be seated for over 12 hours and in the end I come end up beinig tired and ini great pain.
I am 28, 5 Foot 11 and weigh around 105Kgs. Also I smoke about 3 cigarates a day.
Of late I tend to drowse while learning the process and want to desperately come out of it. I have only about 5 hours of sleep and I am now yearning to do my Yoga and get fit soon.
Can you kindly advise me the way to get my yoga practice started and what could be done to avoid the drowsiness

It mights sounds trivial…but

Get some sleep, get rig of 20 kg, and quit smoking…

Go in order.

Some light stretching.

Some light kumbhakas or deep breathing. Kaphala Bhati / shining skull.

Open and relax the body. Fill it with the vayu. Then see whats what.

BE GENTLE.

Do the Yoga at work. Hahaha.

Can you sit at your chair in lotus?

Can you breath deep all the way down to the lower abdomen in your chair?

Can you bring the tounge to the roof of the mouth?

Can you steal a break and not think?

Can you work bandhas at your chair?

Can you stretch at your chair?

Can you repeat your favorite mantra at your chair?

You already said you were doing shambhavi mudra so there’s no need for me to say that the practice of gazing should be done with good guidance.

In the practice of a complete yoga we learn that our living is the sum of our choices.
The human body tends to feel well rested when we eat nourishing foods. As long as we are allowing or facilitating the ingestion of toxins (the ones we DO have control over) then it is to be expected to have a body not at ease (dis-ease).

Nutritionally, I suggest to my students that they eat only organic foods when possible, focus on deep leafy greens, stay hydrated by drinking at least half their body weight in (us) ounces of fortune delight with sunectar or water with lemon/lime and avoid caffeine, alcohol, tobacco, and sugar.

Physically, if you are chosing to remain sitting for 12 hours, I would suggest a simple practice (initially) focusing on gentle backbends and opening of the hip flexors - the psoas, ilacus, and rectus femoris. If you go to Goolge Images and search that phrase you’ll get a solid picture of what I’m referencing.

Specifically I’d suggest vanarasana, modifications of virabhadrasana I, parsvakonasana, trikonasana, supta padangusthasana, ekapada supta virasana, and setu bandha.
