That's my experience with benzos:
I tested my clonazepam, 2 mg had no effect, I only got a bit sleepy the next day, but the sedative effect was very weak. Next night, I tested 4 mg and again I didn't feel any effect (within 1-2 hours of taking it). However, I woke up the next day feeling very sleepy and dizzy, It's like I've been awake all night. Oh, I woke up a few times during the night, so the sedative effect wasn't too powerful.
I also tested diazepam at low doses and the results were the same: a weak sedative effect and a little dizziness the next day.
Alprazolam was the only benzo that really made me sleepy (in low doses). 2 mg is enough to make you sleepy in 20 to 60 minutes, and 4 mg has a sedative effect so powerful that it seems impossible to interrupt your sleep. The next day, you may also feel a little dizzy and sleepy, but these effects are weaker and don't ruin your day.
I was frustrated because, in theory, alprazolam has a weaker sedative effect than these other two benzos. Its purpose is to treat anxiety, but in high doses, the sedative effect becomes very powerful.
I'm now starting to consider just using alprazolam in my SN protocol. 2 or 4mg at the beginning to reduce anxiety, and 30mg at the end to ensure unconsciousness.
The worst thing about alprazolam is that it tastes bad, very bad. If you crush it and mix it with water, it becomes even worse.
Oh, and I have no tolerance for benzo.
