Hi, I'm on Strattera, 60mg. I was on 80mg for a while which worked really well but it made my stutter 100x worse so I went down a little and it's all good now, but not as effective.
It's a fantastic little drug, but very subtle and it took like 4-5 weeks to start working for me and there were some adverse effects at the start. It's not Ritalin, it works all day, there's no comedown but also isn't as "effective", it just subtly increases your executive functioning in ways you don't always notice because it's so transparent. Hyperactivity is also way down. I actually combine it with 10mg of extended release methylphenidate because 60mg doesn't do too much.
It doesn't work for everyone but you gotta give it time, if it does work it can be a godsend.
