The D or DL version will introduce the endorphin/opioid angle, which for some people won't feel good. Increased opioids can make some people feel dysphoric. Other people euphoric. Other people just normalcy.
The L form does not have any opioid action, so it is basically just helping produce more norepinephrine and some dopamine.
I don't think any doctor should recommend any particular form of amino acids, but rather give a manageable list to sample for trial and error. Those choices imo would include 5htp, tryptophan, NAC, DL-phen, L-phen, D-phen, tyrosine, glutamine, and gaba. Maybe the doctor you mentioned has just seen more success with DL than the others in his own practice, dunno.
In any case, you are a master at trying stuff and weeding out the duds, so I am happy to hear you have successfully pinpointed one that is good for you.
