really not much you can do about the tolerance, takes forever to go down as well. Clonazepam doesn't hit hard so most people don't notice it working even at higher doses unless they have anxiety.
are you using them recreationally or for therapeutic reasons? If it's for recreation, your tolerance will skyrocket and eventually no dose will get you where you want. Clonazepam is not a great benzo for recreational purposes anyway, takes too long to kick in, lasts too long and is not euphoric, for most people. Even after an 8 month break i got up to 10mg/day of clonazepam within a week or two, so tolerance returns quickly as well.
if you're looking to get fucked up from benzos then add some gabapentin. tolerance builds fast but you can get pretttty pretty fucked up a few times a month from the combo without issue.
