Short answer: talk to your prescriber first

Gonna push back on this one. Batch-to-batch purity variation is not that straightforward in my experience. I have been on this for 18 months and the reality is messier than the trials suggest.

Don't get me wrong — the medication works. But adherence is harder than people admit. We should be honest about that.

Slightly tangential to Batch-to-batch purity but quinn_sf reminded me — has anyone else noticed changes in their alcohol tolerance?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.
