I have just been persribed Clonazepam and took my first dose today at lunch time. For about 10 minutes I experienced intense sysptoms of hallucinations and according to my partner 'Said stange things'. I then fell asleep virtually comatose for a few hours, and could not be woken even when shaken. Is this normal? I cant remember any of this happening and since waking have slurred speech, and loss of balance and co-ordination.
