Lorazepam IS ativan. There is an injectable form but you probably have little white pills...5, 1, or 2 milligram. Most likely 1.
It tastes like candy, and there is a tendency to eat whole handful of them one after the other. ESPECIALLY if you are the type of person who goes through a box of tick-tacs in an hour.
Its subjective effects are basically like a super-condensed alcohol minus the naseua of drinking the shit.
Its an anxiolytic. Its short-acting. Its a benzodiazepene (like valium).
Expect a 'white-out' of the past 5 years of your life if you start eating them regularly.
You will also start to have problems 'coming up with words' if you use them at all.
Expect antrograde (spelling?) amnesia AND retrograde (spelling?) amnesia.
Expect short-term memory problems, and
That may be a good thing if they were shitty years, but more often than not the bad feeling in your stomach of not remembering much about your life does make you feel like you 'lost' or 'wasted' those years and memories on some drug.
Also expect 'mental dulling' that is to say, turning into an idiot but thinking you are smarter than ever.
All in all- alcohol is more socially acceptable, legal, more fun to consume, fewer long term side effects, and cheaper. And it has similar effects.
In any event, the number of days the effects will last is roughly equal to the square root of the number of milligrams you ate, then subtract .75.
1- 6 hours.
2- 9 hours.
3-1 day.
4-a day and a half.
9-2 and a half days.
16-3.25 days.
25-4 and a half days.
So, watch yourself
