The reason I decided to sample the Source Naturals
sublingual (orange-flavored) GABA Calm, was because I had
found the Source Naturals GABA (750mg) tablets to be
somewhat effective in relaxing my "knotty nerves" overnite
when taken crushed (1-2 tabs) in warm water at bedtime.
After awhile, I'd feel a warm tingling travel to my head,
which is unusual for me, as I usually never feel reactions
to anything. But I guess that's why it sorta helps.
However, unlike the regular GABA, the GABA Calm orange
sublinguals caused me to get soreness under my tongue,
probably due to a combo of the acidic orange, as well as the
rough/chalky texture of the pill. It tastes quite good, but
since it had that effect, and in any case I had a hard time
getting it to actually dissolve under my tongue, I'm
sticking to the no-frills non-flavored regular tabs.
