Sorry to hear that, friend, any condition that is worsened by a common cold is a cruel double attack on someone. I must admit that I have an opposite experience. If i have a fever and am sick enough to consider myself ‘sick’ I tend to stutter a lot less but i think its mainly because I have far less to say when I’m unwell and if I’m talking it is for something very specific and a shit ton of other thoughts are not racing in my mind. (As always, our ‘condition’ shows just how differently it can manifest in each that is cursed with it). Cheers and I hope you feel better.
