So I have ME/CFS, chronic migraine and have just added Fibromyalgia to the collection though I think it’s been there for a long time. One of the symptoms probably belonging to the former or the latter is needing to go to the loo often and in the last couple of years this has definitely worsened. Early last year I was waking up 2+3 times a night for the loo and they tried me on solifenacin which did help but stopped being effective a few months ago and did an ultrasound which was fine. I was and still am waking six times a night which is flipping ridiculous so they tried tolterodine which did nothing over 3-4 weeks except give me dry mouth. I’ve now been on Mirabegron for just over 5 weeks and still nothing. This is playing havoc with my sleep which was already not great. Has anyone had any joy with this? If so how long did it take? They gave me a two month supply and then will revisit it but I’m tearing my hair out here. Or I would if I had the energy. I get an hour to an hour and a half max before needing to get up for the loo again. I’m wondering if more needs to be done to look at the root of this somehow or if further diagnosis is needed too? I've wondered about it being interstitial cystitis possibly which seems to fit but no medics have ever mentioned that. Would be grateful for any thoughts or similar shared experiences, thank you.
