I have been taking clonazepam 1 mg. for years. Recently Rite changed distributor to Accord Health care mfg. Rite aid has changed to your company. They only have blue clonazepam pills 1 mg. I have tried them for 10 days and I am not sleeping. I am a wreck. What can be done for me. Rite Aid tells me they only
have the blue pills.On the blue pill is says C1.
What can I do.?????
