Oh yes! Something that might be worthy of mention is that I personally experienced overwhelm symptoms when I had more inflammation. I didn’t understand why the grounding field didn’t work at times. Fields can create a healthy inflammatory response (which is necessary and part of the healing process) and some people will never even notice it. But for those who already have some inflammation (which can be body and/or brain as any form of chronic stress and things like ADD, ADHD, depression, anxiety, fatigue, etc are all correlated with inflammation) the healing response can lead to fatigue, brain fog, etc.
Usually I experienced energetic overwhelm in the form of tension, racing thoughts, being wired but tired and having difficulty sleeping. Whereas inflammation overwhelm was felt more as fatigue and brain fog, lack of motivation and overall sluggishness (but I can’t say it was always the case as I only noticed the pattern in hindsight and I don’t know how it translates in other people).
Might be worth trying anti-inflammatory fields to see if they help, you might have another arrow in your quiver to increase your fields capabilities 
Any of these shouldn’t create overwhelm:
-brain and spine antioxidant complex
-nerve inflammation help
-ear inflammation
-blood brain barrier repair
I’d pick 1 of the full body ones (the first two) and 1 of the brain ones (the last two) and play each twice at the beginning of the playlist and give it about a week see if it helps
