The doses are not high enough to cause you any serious worry. It sounds like you're at least somewhat familiar with benzodiazepines, so you would know if you had an unusually high sensitivity at this point.
Like the above poster mentioned; Ativan (lorazepam) is one of the shorter acting benzodiazepines. 6 hours is a rough approximation of how long I can feel/notice the effects. Klonopin (clonazepam) on the other hand, is a longer acting benzodiazepine (there are even longer acting benzos; chlordiazepoxide, diazepam, oxazepam etc). Dependent upon your stomach content at the time of ingestion, 3 hours should be ample time to reach the peak effects. There is a good chance that for a full 24 hours, clonazepam will be exerting some influence on you, even if it's very subtle.
Example: I'm on MMT, but rarely mess around with Benzodiazepines. Due to a seizure I experienced recently, I was given a prescription of Six (6) measly diazepam 10mg pills. Naturally, I consumed the 3 day supply in the pharmacy bathroom. I had dosed my Methadone (90mgs) previously that day, but didn't experience any heavy sedation/black outs at all. I just felt very relaxed. I woke up the next morning, feeling that the effects of the previous evening's Valium dose had completely worn off. I went to the clinic that morning and drank my dose. I left the clinic, got in the car, and within 5 minutes of dosing I was unconscious and unresponsive; completely blacked out. I ended up sleeping all day 9-9, woke up briefly and had a snack and then slept for another 12 hours.
Keep in mind, I did not take any benzodiazepines that morning that I dosed, this was all because of the diazepam I had used about 18 hours prior. Make sure you keep your benzo dosages safe and within reason according to your own tolerance. Also keep in mind my story, if I had been behind the wheel of a car, I would've crashed and I felt zero effects from the Valium before I took my dose. Thought I knew better, but I was wrong. Sorry for rambling and good luck
