Thanks for your question on Healthcare Magic.
I can understand your concern.
Your all symptoms are suggestive of
sleep apnea due to obesity.
The machine you are talking about is known as CPAP machine.
It is best treatment for sleep apnea.
But along with CPAP, you should also focus on weight reduction.
So better to consult dietician and follow strict dieting schedule.
Do regular
aerobic exercise like running, cycling, swimming etc.
Also ask your doctor to increase pressure in machine according to your need. Once weight reduction is achieved your need for machine will also reduce.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
