why do i always talk sense when im drunk?

ok im kinda a shy person and cant ignite a converstation let alone start one, but when ive had a drink the truth comes out, and i tell things how it really is, whereas if im sober i wont talk about things incase i hurt peoples feelings, my thoughts and feelings generally get suppressed when im sober, its just the way i am

but i dont get it, like when most people drink they blabber a load of old cods wallap, whereas if i have a drink it seems to "normalise" me and helps me get out whats on my mind.

i can string words together that actually mean something, and my inhibitions are set free
i find it difficult to put my thoughts into speech, i think im dislexic to be honest but havnt been diagonosed
