na, sorry. i don't have access to medical journals anymore -- at some point my alma mater realized i'm no longer a student and cut me off from the online library. i remember, years ago, trying to find articles along those lines. most studies involved absurd doses in lab animals -- actually, sometimes they skip creating tolerance and inject the chemicals that benzo WD creates -- to create lesions. for some reason they will not experiment with humans. case studies (that i found) are worthless in this area. so i cannot cite anything proves that 15mg to cold turkey is not safe, but articles that suggest this are abundant. if you are experiencing WD from benzos, you are experiencing excessive glutamate activity, which is linked to excitotoxicity. that's all i need to know to shoot for the lowest dose before none.
i didn't take it personally. you (kinda, indirectly) asked my reasoning, and there it is. also, i didn't drop down to 12.5mg today. maybe this weekend. work is stressful enough as is. key for me is to never go backward. sticking around at the same dose for longer than intended is not something i criticize myself about. shit, i think it's still progress.
best in your recovery.
