Shedding, Prilosec OTC and Regurgitation

Sidney is wore out from partying on New Year's Eve!!
So, Sidney has been shedding A LOT lately. He is a Lab, that's the deal, I get it. And also lately, he has had some late-night regurgitation issues or late-night issues where he woke up at 3am and just looked uncomfortable. Some afternoon episodes too, but those are rare. His recent regurgitation looked basically like it was from him ingesting his shedding hair. He licks his paws a ton and somehow ate a bunch of his shedded hair. I am hoping that his recent episodes are just that. EPISODES. I feel like they were isolated because he seems super fine outside of this. He played with my friend's Black Lab Cisco on New Year's Eve for the ENTIRE night and could not have been more energetic or more happy. I cannot stress how HAPPY he was. He loves playing with other dogs so much. Once his favorite dog park Bow Wow Beach opens back up next year, we will be there every week!! So basically, Sidney is doing great, I just always worry about him when he has a bad day. Way over protective I know. But I have to be. It's my obligation to my favorite buddy in the world.
On another note, I have been curious about long-term Prilosec OTC usage and the effects. Only because I have seen commercials that state to only use for 14 days at a time and a cycle of 14 days every 4 months (in the fine print). Sidney has been on it for 2 years straight. I will do some research online. However, since it has helped with significantly decreasing regurgitation and the potential for Aspiration Pneumonia (which can KILL him fast), the risks are most likely worth the reward of his life being extended for around 13 more years. I'm no expert, but want to make sure what we do for Sidney is always the best for him. So I am going to ask the vet and my actual people doctor about it to be sure. I just do not want to potentially create a new health problem for Sidney since he obviously already has a stupid MegaE problem.
Happy New Year. Sidney has already had more than he was predicted to and will have many more. Megaesophagus is NOT A DEATH SENTENCE!!!!!!!!!
