in public? course it's fine! as long as there aren't any little kids around watching me, I've even done a shot at the bus stop! it's not like you're doing drugs. i do my tests and shots at my cubicle, my co-workers don't seem to notice or care. i even take shots in the car while my boyfriend's driving! I do shots outside of the bar sometimes while my friends are smoking and we're getting air even!
in restaurants, unless I'm at a booth & there's kids close enough to notice me, i generally go into the washroom but never in the stall unless i need to pee anyways.
i prefer to stay out of washrooms when doing my shot because i find it's dirty. if someone has a problem with me doing a shot in front of them, that's their problem not mine.
i only avoid doing it in front of kids(under 10) because sometimes it bleeds and some kids are really scared of needles and i don't wanna freak them out.
i test my sugars wherever. bus stop, while walking, in a store, at the table at a restaurant..wherever. if i need to test, i test!
I do my shots in my tummy, my arm(sometimes) and my thigh. if i'm in public and i decide to do it in my thigh, i just do it through my pants or lift my skirt/dress up a bit on the side..it's not like i'm gonna flashing people. if i use my tummy, i just lift my shirt up a bit..again, not a huge deal.
at fairs, i used to go to the washroom, just because all of the kids and when i was a teen, parents would give me scary looks..of course cuz they thought i was another teenager getting high in front of their kids..but about a year ago i went to a local fair and i was gonna go into the washroom but there was a huge line(also..they are super gross cuz they are public park washrooms..so i didn't really wanna go, i hated having to do that) cuz there were SO many kids but i was eating cotton candy so i HAD to take a shot. my friend got really upset that since i was a teen, i had been nervous to do a shot at the fair..so he made me sit down at a picnic table and do my shot. him and my friends stayed with me, and he said he'd rip anyone's head off that gave me a look for doing my needle. haha.
i use vials and needles, no pens. pens actually freak me out. the clicking mostly is what bothers me.
