The ReBUILD doses were rather high though (10 tabs a day!). 1 tab would probably do it over a few months.

The data suggest correlation, not necessarily causation, but at the least I'd carefully investigate the risks before taking any anticholergic in such high doses. I do understand (with my own chronic health issues) that even with the risk of dementia later on, it may still be a possibility, depending on the severity of current symptoms.
Thanks, I've never even heard of clemastine, and it's rare to find anything notable that doesn't require a prescription in the UK! I already take another gen 1 antihistamine at night (they are very sedating for me), so I guess could swap it for clemastine.
Now all I need to do is convince someone to give me a prescription for metformin...
