"this drug should be taken at the 20mg strength.  the trials were done at 20-60 mg, but the fda forced merck to make 10 mgs (that do not work but do cause side effects).  there&#039;s a long article in the new yorker about all of this. my main problem with this drug is that it&#039;s hit or miss.  it shuts my mind off very well, but sometimes i wake up only 3 hours later. even if it&#039;s 8 hours, i can be very tired the next day. but, sometimes i am great the next day!  the inconsistency didn&#039;t improve after 10 days. i am also on klonopin, cymbalta, and neurontin, but i cannot stop those. the trials were biased because they only allowed &quot;pure&quot; insomniacs not on any other drugs or with any other conditions...how many people are like that?"
