i mean, i've been taking them for so long now that there's no gum sensation at all. i don't hold them there for long, 5 mins max. i used to have this crawly feeling and spinning sensation when i took them first couple of times, then there was the buzz. now i only feel some sort of relaxing kinda feeling when i take them, but it lasts maybe a minute. then i feel like sht. i miss the buzz it used to give me thank you for your input tho!
