Well, that's not very definitive.
Also the statement that histamine plays a role in arousal is so (can't think of the word, could mean anything basically; open to interpretation) if you're talking about sexual arousal that's sort of true but has nothing to do with LDing anyway. If any part of what you said to do plays a role in getting an LD it would be the Pantothenic acid and B vitamins.
Just quote from wiki.
Sleep regulation
Histamine is released as a neurotransmitter. The cell bodies of neurons which release histamine are found in the posterior hypothalamus, in various tuberomammillary nuclei. From here, these histaminergic neurons project throughout the brain, to the cortex through the medial forebrain bundle. Histaminergic action is known to modulate sleep. Classically, antihistamines (H1 histamine receptor antagonists) produce sleep. Likewise, destruction of histamine releasing neurons, or inhibition of histamine synthesis leads to an inability to maintain vigilance. Finally, H3 receptor antagonists (which stimulate histamine release) increase wakefulness.
It has been shown that histaminergic cells have the most wakefulness-related firing pattern of any neuronal type thus far recorded. They fire rapidly during waking, fire more slowly during periods of relaxation/tiredness and completely stop firing during REM and NREM (non-REM) sleep. Histaminergic cells can be recorded firing just before an animal shows signs of waking.
Sexual response
Research has shown that histamine is released as part of the human orgasm from mast cells in the genitals. If this response is lacking this may be a sign of histapenia (histamine deficiency). In such cases, a doctor may prescribe diet supplements with folic acid and niacin (which used in conjunction can increase blood histamine levels and histamine release), or L-histidine.
