Suboxone hadn't has an effect on my HRT, and no they won't find it even if they do test you for drugs (not my finest moment but the RAN never found it and they do some hefty tests).
I am furiously trying to drop Sub all together, though, as I'm supposed to quit for surgery. It has helped so much, but then so has transitioning. Being trans was the primary issue unaddressed issue that led to my opiate addiction. Drugs numbed the dysphoria...at first...and dealing with the dysphoria issues rather removed my desire to use at all, tho like a good addict I'm still very careful around any pills (oh and get this I do tell my doctor to please not prescribe opiates...ha never ever thought I'd say that!)
As they say...drug abuse is merely a symptom. Quitting suboxone is happening at a natural pace the more I deal with those issues....ha do I ever knowwhat it's like so, of course, youre not alone! 🙂
