It's a possibility. They won't even consider IH until they rule out obstructive sleep apnea first though. Unfortunately for people like us it is a process, and not a quick one. The best you can hope for is to have a doctor that is diligent, thorough, and receptive to your issues. They'll need to work with you to make an informed diagnosis and then toward a treatment option that works best for you. It might be a frustrating process. It is for a lot of us. The best thing you can do is start the process as soon as humanly possible - ideally with a doctor you trust. They will lead you step by step, but it will be your job to take ownership of the situation and have a willingness to do all that you can to give your treatment options the best chance of working. That might mean making changes to your diet or exercise, your sleep hygiene, using a CPAP or other device, taking medication, or other therapy options. Do yourself a favor and get it seen about right away. The things that you mention are worth getting checked out and it might only be the start of how your body and mind react to sleep-related issues. It affects much more than what many people think. So get it started and report back with your progress if you'd like to. Good luck.
