shots :(

im not new to drinking but shots i find unbearable but i want to get better, how do people stomach them? when drinking with my boyfriend he loves shots and prefers them to drinking but when i try it activates my gag reflex so hard i have to take half a shot and even then its unbareable, but also i suppose we buy the cheapest vodka because were young and moneys tight. is it just a certain breed of human can do shots without wanting to vomit or is ot someting you learn with time and practice. i love making drinks and find getting drunk that way waaayy easier but i dont like the fullness you get when youve had like 2 3 drinks, because i dont drink a lot anyway like not just alcohol like i just dont have the bladder room so shots sound good because you dont get a full bladder, sorry ive had some to drink i realise this is a ltitle rambly
