im not a specialist of extraction but i think its better if you have the plant with the right effect in the first place.
In a home made decarboxylation you always loose some terpenes and possibly convert THC to CBN if heated too high or too longer, but still, a cerebral sativa hybrid (or pure sativa) plant dercarboxylated will not transform into a couchlock or sleepy effect extract i think unless you loose all the terpenes and degrade a lot of the THC into CBN.
You can experiment an extract from sativa leaning plant if its the only strain you have access to, maybe you will find it will do the job for you.
personnaly most of the time i only smoke sativa dominant haze hybrids and i sleep like a baby, just a mater of dosage, im still searching a strain with the effect of cocaine
: in fact i was reading a little more about CBN, im not researching the sedative effect too much in cannabis for myself but i just read CBN is good for insomnia so as CBN comes from degradation of THC maybe it will be interest you. as i said THC degrade to CBN when you decarb too much. again im not a specialist of extraction so maybe what im telling is not totally acurate. here are some links. all the best to you
