Some friends invited me to go camping next month, but I'm a complete zombie until the sun sets. I wake up with a bloated stomach, physically feeling like I'm going to pass out, like I've just ran a marathon. Walking up a set of stairs is physically exhausting. Now the physical exhaustion sucks, but I can deal with it. Usually going for a 6mi run gets me half-way to feeling normal.
The real problem is the mental exhaustion. As I mentioned, until the sun sets, or about ~12 hours after I wake up, objects around me are all blurry. It feels like extreme disassociation coupled with literally zero short-term memory, like not being able to remember what you did three seconds ago. This has gotten worse over the past three years, despite me getting in better and better shape (in 2019, I would wake up feeling energized despite weighing 170lbs and having a shit diet).
I'm 23, 5'11, 150lbs. I have a healthy diet (get protein from meats, sometimes tofu, avoid gluten, carbs from rice/potatos; and I avoid processed food), my sleep quality is good (get 8-9h a night), take proper vitamins, etc.
In terms of supplements, I have tried each for at least a month: CBD oil, anti-inflammatory supplements, GABA, nootropics, stimulants (modafinil, ritalin, adderall). Nothing really helped.
Diet-wise, I have tried keto and carnivore, each for two weeks. On them, bloating and physical exhaustion weren't as bad, but my mental exhaustion was considerably worse (it felt like half of my brain completely shut down, even at night)
The only thing that made me feel remotely normal was fasting, but obviously this is not sustainable long-term. It's like my body is allergic to sleep. Fucking hell.
The closest doctor is a four day hike away (I live on a farm without a working car, and in the past mayoclinic has been more helpful in diagnosing problems than my GP has)
Right now, I need to go for a 8 mile run every single morning to not fall asleep an hour after waking up. Any suggestions?
