I've posted this question other places and asked people I know but absolutely no one has any idea how these two substances interact. I have a lot of these "gabas" under the brand name Neurontin and they provide a great sense of well-being and happiness similar to mdma. There are no physical sensations like mdma except for a slight head buzz and a bit of disorientation like when your a little dizzy and turn to look at something too fast, but they do help with pain. They're great for anxiety too...popped 3 300mg tabs a couple hours before an interview I had been nervous about and walked in there talking and laughing with them like they were my best friends (got hired on the spot too ). Back to my question though...has anyone experimented with these and mdma or know anything about how they might interact? Erowid describes gabapentin, 1-(aminomethyl)cyclohexanacetic acid, as being an anticonvulsant/tranquilizer...."Gabapentin is prescribed -- usually in combination with other medications -- for the treatment of seizure disorders, though its anticonvulsant mechanism is not known. It is sometimes prescribed for the management of neuralgia (nerve pain) and has been prescribed off-label for the treatment of mood disorders, anxiety, and tardive dyskinesia (a neurological syndrome caused by the long-term use of neuroleptic drugs)."
