As for the original question, I came across a quick Google search for the LD50 (lethal dosage) of Klonopin (in mice, ha), and it was listed as >4,000mg/kg of body weight. So to make you sick, let's dice up the number to 1,000mg/kg of body weight (25% of the lethal dosage, which would be enough to cause severe sickness (among other things), I imagine). Let's assume you weigh 150lbs which is about 68kg. 68kg x 4,000mg/kg = 272,000mg, or #136,000 count 2mg tablets of Klonopin. I doubt that many could fit into your entire digestive tract (from entrance to exit). Besides, even if you had access to that much Klonopin, you could sell it and live off the profit in peace at home
Realistically, though, I don't think there is an amount of Klonopin that anyone is going to be prescribed for SA that could ever make them severely ill. As I think others have pointed out, you'd probably pass out and sleep for a while before becoming sick.
Xanax is what works for me, but it does require multiple daily dosing for particularly bad SA-provoking situations. Lately, I've been taking only 1mg during the day to ensure no withdrawal occurs and then a couple mg's at night for sleep. Once I start an upcoming job and eventually return to school in the fall, I will probably be back up to 4mg-5mg per day. It's not troublesome, though. It depends on you and what you're willing to do, I guess.
