You are proposing to do exactly what I have just done.
I was prescribed Lyrica some time ago but there was such a lot going on at that time with my Mam (alzheimer's) and my Dad and I were trying to care for her at home as no 'care givers' could cope with her. She is in a care home now so things are much less stressful. I think at that time I was just SO exhausted that I found the Lyrica actually worked too well and allowed me to sleep at night, but I was so knocked out (exhaustion?) that I don't think I was even moving about in the night and was waking up with muscle pain, where I had never had muscle pain before??? I still don't really understand what was going on but had read that muscle pain could be a side effect. As we all know mornings are our best time so I decided to stop taking the Lyrica to at least get my early morning 'ability' back.
Anyway I decided to start up again and must admit that I didn't ask permission from anyone, pain consultant or whomever. BUT I think because I have noticed a slight benefit from this drug (mine are only 25mg's too) after a bit of a conflab and confusion, I have been prescribed it again.
This drug is often difficult to get prescribed due to cost issues in the UK (NHS) so the fact that it was helping me must have influenced their decision to keep prescribing it.
If I were you I would start taking them again and see if they work for you (ramp them up slowly if you find the space you out, or give any other difficultish side effects)
They do have a spacing out effect on me but I am taking 75mgs per day now, although I didn't have any for over a week of conflab and confusion, already mentioned. So now know that withdrawal at that level isn't so bad either

I think that it would be very informative for your up and coming appointment to be able to give any information about how they do work for you, although it may be to soon to have too much feedback on good pain reduction, any side effects (like your bladder issue and my muscle pain) may be apparent by then. The way to treat this with medication is to try and assess, your own feedback can only help medics to know how to proceed and treat you.
I am a bit spaced by them, but did expect that and have a dry mouth but have experienced no muscle pain when waking this time thankfully.
Good luck next week,
Helen
