I don't think plugging it is the best idea. Maybe put it in a sweet drink so you can't taste it.
It is likely overuse & tolerance that has made it ineffective, maybe you should think about switching to a longer acting benzo to taper off.
I notice you have another thread with you complaining about different potent benzos not working, do you really think it's the drugs not working & not your tolerance? You need a reality check.
