Hi RorschachSwe, the same exact thing happens with me. I love Omega fish oil just for the general benefits;skin, brain, hair, acne, etc. BUT it does make my stuttering worse immediately. I have tried many brands too but I get the dame aggravated stuttering. You should try nofap for stuttering. I know it's random but many people have said that nofap helps there stuttering a lot. Peace.
