Hey there friends! I got a part of my brain back (now on Concerta) and with a clearer head I was reminded of how much I disliked the word 'journey' to describe this BC road I'm on. I feel like it's something my highschool guidance counsellor would say, who has never been on this path before. Ju
Hey everyone! I said I was gonna keep you updated and I'm doing just that, again! Such good news and I can't stop crying happy tears! \------------------------------------------- MY BACKGROUND: I was cancer free for nearly 5 years since 8/28/20 (ER+/PR+, stage 2 invasive ductal carcinoma to left b
I've been thinking a lot lately of what future treatments for hormone positive breast cancer will look like. The estrogen blocking standard of care dramatically effects quality of life and eventually stops working as the cancer becomes resistant to the hormone therapy or mutates as a result. Menopau
Hello, I posted here a few months ago about how awful the hormone therapy was, and it was so helpful to hear that so many people had the same experience. But also so sad. So I'd like to share some things that have turned the situation around! I'm on exemestane and ovarian suppression and at 44, wa

1 year on Kisqali, Exemestane and Lupron after completing 6 x TC and radiation, and this is not to scare anyone - but what started as "I can do this! It's not too bad" is now more of a "what the actual flying FUUUCK am I supposed to do with this shit" experience. Of course the low mood, hot flashes
There are many anecdotes on the internet of people having worsening of anxiety, depression, and libido issues while taking Anastrozole, even when their E2 levels are in the normal range or above. I am one of those people and there are several reasons for this that I want to share. For the record, I
hello again and happy grinch season to all my haters. i am back with a part 3 covering some of the stuff that is “extra”, that is, the stuff beyond nutrition recovery and training (which we covered in parts 1 & 2). again this is an **effortpost** and i know it’s cringe but there is occasional ch

I'm by no means a medical professional but I did a lot of online research, Reddit thread reading, and got some great tips from my clinic. I wanted to collect the best info in one easy place because this subreddit has been a huge resource to me during this process and I wanted to contribute where I c
My husband and I have been trying for a baby since 2016. We spent 3 years trying to conceive without a single positive test, then turned to a fertility clinic and tried everything from letrozole to IVF with PGT (2 rounds). We experienced many losses in the first trimester and had an ectopic pregnanc
I just wanted to share this in case it helps anyone. I will start this with a few things to keep in mind. I am on 10mg of letrozole, 500mg of metformin (2x per day), and I've been taking the trigger shot now for 3 cycles. Perhaps this is a coincidence, but I (largely) cut out carbs and sugar from m
I recently went to a pcos information day. It was a really interesting experience to see so many different woman of all sorts whom all had pcos. There were talks with gynecologists and professors. Some information I got from that day: - If you want to treat excess hair with laser, it doesn't work if
Today, I am throwing in the towel. I'm done. My period was one day late. After 14 months of trying, and my first month on Letrozole, I thought "This is it!". My body amazes me every month with her variety of PMS symptoms that I mistake for pregnancy, but Aunt Flow never lies to me. I dutifully pee o
I have a 17-month-old daughter, and I’m currently pregnant with another girl due at the end of March. Without question the last year and a half has been the hardest period of my life and almost none of it was due to newborn life or typical first-time parent struggles. To rewind a bit, about two year
Hi, I'm a UK tech, have been for about 7 months now so still relatively new to it. We have a handful of patients on letrozole but each one wants a different brand and won't have any other. It can't be that they just don't like other brands e.g. Sandoz Amlodipine over Almus, since they all share the
An MD said it is ok to dispense both. What are your thoughts? Do you feel comfortable doing so?
