Hey,
At what time do you take the glutamine?
I take Vyvanse in the AM and I take glutamine at night before bed as it’s also known to be a sleep agent and it’s never given me any issues.
Of course everyone is different. That being true, if you hadn’t already, you should definitely spend money on intolerance tests/advanced blood work/nutrient deficiencies etc.
I’ve found for me it’s not what additional things I need to take, but removing the things that prevent me from being optimal.
Good luck!
