Rivotril / Conazepam will be a huge help and Godsend for sleeping post meth. Benzos are antithetic to meth and in general cancel meth out (dose for dose).
There are some factors to consider here
- how much meth and when was your last dose?
- do you have any benzo tolerance?
Either way yes, it will help you A LOT to come down and sleep but still needs to be used properly.
Be wary of taking Rivotril and then deciding to drive a car, for example. Delusional sobriety may cause you do to stupid things like crash a car. This needs to be noted.
Otherwise, it's a great drug to come down from meth and sleep.
When you decide it's time to sleep take some Rivotril and then GO TO SLEEP - don't decide you're suddenly hungry and drive. When you take benzos to end a meth high you should be ready to sleep and not need to leave the house.
You'll be fine.
