There really is no maximum dose, you can take as many as you want and not die(unless mixed with booze or opiates or some other downer) but I don't reccomend that, cuz you'll just black out do dumb shit and afterwards be like that sucks. Do you have a tolerance?? Guesing not since you are asking about it..so I would say start off with 2mg. Takes about and hour/hour and a half to kick in and just makes you calm, if you are not an anxious person, then just expect to feel sleepy. I went without benzos for about 10 days, was gonna keep goin but went out and got some Klonopin(was hopin for xanax) ate 12mg yesterday, 10mg the day before, and 2mg when I got home from work just now, it has a long half life so I am still feeling the effects from the other doses(NOTE DONT TAKE 10mg!!!! I have a tolerance and have been taking benzo's since I was 14(not prescribed though.) So just start with 2mg,(chew em up, they taste like mints, or what I do, hold them under tounge because they seem to kick in faster. Then put on a movie and chill, there not very recreational, just relax you. AVOID ALCOHOL AND OTHER DEPPRESENTS.
Edit: Also, I would say 1mg of Klonopin is like 5mg of Valium. Xanax and Klonopin are eqipotent though so 1mg of Xanax is 1mg of Klonopin.
