Struggling with Strattera Side Effects

I’ve been struggling with side effects on 100 mg Strattera after a long slow titration beginning at 25 mg. Will the insomnia, fatigue, headache, acid reflux and heart rate increase ever go away? I was doing fine at 80 mg but after 2 weeks at 100 mg am still struggling. I started taking it at night but doesn’t seem to make much of a difference and the insomnia is probably worse.
