pink, I've heard that one can build up tolerance to the benzos, so your experience is probably not unheard of. I'm not sure I understood, but you aren't trying to equate the same mg of klonopin to your sister's xanax, are you? They are different meds of different strengths. Do you feel you need more klonopin each day or are you happy with how the 0.75 mg is working for you? By the way, I have Xanax, 0.25 mg, and can't take it during the day because it puts me to sleep immediately. Sometimes I take it at night to help with sleep, and I cut it in half and take only 0.125 mg. That is great you do not have withdrawal symptoms ever with the benzos, as I've heard that can be very hard.
