Just a quick update everyone.
The 10mg amitriptyline helped a little but, although allieviated, my IBS-D was still bad. Another phone consultation with a different GP led to me increasing my dose to 20 mg and the IBS was so much better - I managed to add beans and pulses back into my diet every other day, and increase my veg intake. However, at 20 the dryness did start to bother me. I saw another locum GP a couple of weeks ago as my hot sweats were also back and I was still experiencing occassional light spotting (after 9 months on mirena coil). He checked with another GP, and as I've only recently had a smear we're going to monitor the spotting and possibly increase progesterone, but in the meantime I've increase to 75mcg estra (which has been great). He prescribed me some eyedrops, but also suggested that as my IBS had generally calmed down I try skipping the amitriptyline to see if it helped relieve my dry eyes and skin. I've not taken any since Monday, but now I'm struggling with sleep - grrr! I'm exhausted by bedtime but then spend at least a couple of hours doing a succession of tapping exercises, guided sleep meditations, yoga nidra for sleep, etc., and then once I do drop off, I'll wake a few hours later, and then I'll wake up early too. I hate feeling reliant on medication, but I think I'm going to need to take some tonight as I'm getting so tired during the day now. Any advice?
For background, I'm physically active during the day and also use a rebounder for exercise, I take magnesium byglycinate, sea buckthorn oil, omega 3, vit D, B-complex, turmeric, andrographis, and rhodiola rosea. Rather than turn back to the amitripyline I wondered about trying anti-histamines before bed (I'm allergic to sawdust (which is a total pain) and have been cutting wood this week, so I think I might have answered my own question! I'll try anti-histamines tonight and see how it goes.
I'd still welcome any other advice
As an aside, the locum GP I saw was a lovely and understanding older gentleman (from how he introduced himself I think he might even have come out of retirement to help with the winter pressure on the NHS). He made me smile when I said I'd found the vagifem so beneficial and he replied "yes, it can be very good 'down there'".
