its possible that if youre allergic a low dose wont cause a rash but is still causing other bad effects. like how my cousin went on an allergy elimination diet and discovered her acne went away, and when she introduced milk she got sick from having a whole bunch but she also saw her acne came back. allergies are pretty weird

i havnet noticed any change in sex drive on my meds but i already have a naturally low one. if you want to tell your doctor but youre really embarrassed you can write it down and hand a note over, thats also embarrassing but in a different way. i have a friend with a severe anxiety disorder who has to do that with all her doctors because she cant say her symptoms out loud. personally i write it down to feel better and usually dont need to actually hand it over. but often after appointments when i look at the list i realize i forgot to mention something that was on there so i probably should be using it anyways for memory reasons... anyways i don't know how helpful that might be for you tho but its a thought
