Where can i buy a medical cabinet so I can keep our drugs in a safe place.

yes it is too much for almost anyone
max i was on on my worst days was one 25 mg a day
it is an addictive ****
this dosage needs to be monitored and administered by that patients psychiatrist or her known GP that knows her medical history

any of this group of medications should be increased slowly
to suit patients condition

that dose it will deep sleep the patient or keep her very quiet

Yes you can buy medical cabinets with locks. In fact nearly all cabinets come with locks (either keys or just child-proof locks). I've seen them in IKEA and they came in at least 3 colors.
