On 2mg klon bid. klon takes 2 long to take effect & wears off hours before next dose. want to ask doc switch 2 ativan (lorazepam) 2.5mg tid. reasonable?

I'd let doc choose: I understand your problem and the rationale you're using to get there. But I think it would be a better option to allow the doc to make their own choice if in fact, he/she knows your case well. There could be better medication available to do what you need taking into consideration your specific other medical conditions, etc. Good luck.
