Sleep Apnea Treatment

I want to show that I don’t have symptoms so i dont loose my job. I am halfway thru a career and dont want to throw it away. Any suggestions are very much appreciated and will most likely save my career.

Sometimes I will wake up in the middle of the night gasping for air. Other times I will be lying in bed and have trouble breathing through my nose which will create pressure in my head. Also sometimes a part of my body will twitch usually my legs, The only thing that helps is if i sit up or stand up but when I lay down these symptoms will occur.
I am 6 ft. 135 lbs. If anything I am underweight.

I’ve been reading up on this condition, however, I am still not sure if that may be my problem. I do not want to go to the doctor for no reason. I was hoping that someone with this condition can help me find out if I do need to go see a doctor.

My symptoms are sleepiness during the day. Some days I am so sleepy that I am irritable and just not fun to be around. I am usually tired like I had no sleep the night before or as if I had been doing a lot of work, which is usually not the case. I cannot remember a night when I got less that 8 hours of sleep. I usually get 8 to 10 hours every night. Mostly 9 or 10. However, when I get up, I am dizzy and tired and I definitely do not feel well rested. I think twice before getting out of bed because I still feel tired. When I do get up I do not usually feel sleepy then, only tired. It is during the course of the day that i become sleepy. Sometimes very sleepy that I have to get up and do something or I will fall asleep. I am always tired.
I forgot to add that I do not snore, at least I don’t think, but I really don’t think so.

I am not sure what is the cause of my constant fatigue.

Lately i have noticed how cloudy and foggy headed i feel. I occasionally get lightheaded and dizzy. Plus my family says i snore much louder than usual. I also never feel satisfied from a good good nights sleep. Please help. Oh yes…..i am somewhat overweight.
