Have your ammonia checked at a hospital (not a regular lab). Ask
for two requisitions, one
for fasting and another
for post-prandrial (ie. go 20-30 minutes after you consume a high protein meal). In most people, the elevation after eating is mild and in others (like myself) it results in hyperammonemia causing fatigue, encephalopathy, dizziness, ataxia, brain fog, and other neuro issues.
