g'day,I am type 2 but with reading and research have realised I definately have had type 1 often,as the others have said,the same for me,my main symptoms are talking more than usual and really fast,cause the ideas in my mind go to hyperdrive,the brain just goes 100 miles an hour,and as mentioned you want to communicate it all,in a hurry,you become very energetic,happy as anything,confident and as also mentioned love everything around you,it's a great buzz but the sleep goes haywire and thats when the problems start with the down side.You feel on top of the world.
