Letrazole

Thanks for that Kath, I'd googled & found them as well. I have a gf who's a naturopath here in Brisbane, I thought I may ask her if they stock that or similar. 
I also found this one

I'm allergic to most regular lubricants, I use one that I get from adult stores that comes from the U.S. called J-Lube, you make it up with boiled water and don't keep it for long periods of time, there are no preservatives in it, and i don't get any allergic reactions to it, which is great! 
I seem to have reactions to I believe it's the Parabens they use in most lubes. 
Looking at the chart on the YES VM site, it looks like that one would be good for me as it seems so many have Parabens & other stuff that could cause me issues.

Now to find it somewhere near me! LOL 

I'm suffering a lot with bone pain today after my last chemo, as well as the neuropathy in my fingertips & chemo fog. My partner was on a graveyard shift last night, so 1am - 6am, I had trouble getting to sleep, so i'm sure the lack of sleep has not helped any. 

Thank you everyone for your replies, very much appreciated. 

I’ve been on Letrozole 12 weeks now and managing ok so far. I walk daily for an hour and do gentle stretch/ balance class twice weekly plus now doing hydrotherapy Encore class once a week for 2 hours. I also take Caltrate Bone Health 2 per day and am on 6 monthly Prolia injections as was osteoporotic when I started Letrozole. Walking helps a lot with my head space and joints - I find I can walk thru the odd bits of joint pain .Only real problem I have noted is my usual very low cholesterol has more than doubled so am trying to be very vigilant with what I eat rather than statins which caused major memory problems after 6 months - I do take low dose aspirin daily too . My oncologist recommended krill oil for joint pain- have purchased but yet to need them.

I have to be really careful with what lubricants I use. 

I use the Replens lubrication and find it good, but I also need to use a vaginal wash and daily external moisturiser too to prevent the outer skin drying out and hurting.
The best thing I have found after suffering very uncomfortable sex for quite a few months was the Pujr water based lubricant. Bought it at an adult shop while on holidays and it made all the difference.
It has actually helped my libido because I am not afraid of the pain which kills the enjoyment stone dead.
Now just to get over the chest infection and radiation burns and I might feel like going there again.

A holiday with just 2 of us cured our timing and got us back on track. I did try "replens" moisturiser  applicators. You use it twice a week to start with. Like moisturising your face...needs regular application. I have heard the "yess" products are good but only available on line. As my issue has settled I haven't bought it. 

Hi @MKitty68, I will be starting on that soon too. I have another week left of rads and then I guess I will have to take this Crap. Hope it works well for you with minimal effects. Chemo has left me  with aching joints all over so am nervous to start it.

oooh i'm yet to start watching that.... may have to give that a try! *grin* 
I've had topical estrogen, which he's said I could use during chemo from time to time, but i've no used it at all as i'd need to time it between his T shots, his often weird work hours & my chemo. 

Taxol killed my libido. I did find a few months on the dryness improved a lot (which seemed to help the actual desire weirdly). My husband has testosterone injections too so we have our struggles. A netflex night of "outlander" can help.  :D
