For me atleast, my stammer gets worse and better over time. Some weeks it'll barely trip me up but others I won't be able to get a fluid sentence out. My advice: keep your head up, talk to people about your stammer and those who are close to you will understand and supportc you. I've also been down the smoking weed route, and I have to say that you get bored of having brainfog after a while. Stay strong.
