Feeling like a zombie on strattera. Does it get better?

I finally got a diagnosis last month and my doctor prescribed 40 mg of strattera. She warned it might make me sleepy and told me that if I can try taking it at night if that happens. At week 1 I noticed I was dozing off while watching TV and when I went to bed I'd fall asleep quickly. At week 2 I was ready for a nap anytime, and was starting to get moments of feeling a little dizzy or light-headed. One of the times it happened was while I was in Walmart so I spoke to the pharmacist to check if it interacted with any of my other meds. She said I should be fine but that this was a common side affect until the body adjusted to the medication. I started taking it in the evening instead to see if that changed anything.

By week 3 I felt like a zombie. Yesterday I woke up at 8:00 a.m, ran some errands and by 1:00 pm I couldn't stay awake. I set an alarm for 20 minutes to take a nap and slept through that alarm until 6:30 p.m. Got up, ate dinner and crawled back into bed by 9. I didn't actually sleep well, I kept dozing off and waking for a bit and any time I tried to do anything I started zoning out and dozing off again. This went on till about 2 am when I finally managed to stay asleep.

The last time I was this tired was before I got a sleep apnea diagnosis. I used to doze off easily back then, but it was never this bad. Ever since I got my CPAP I haven't had any issues with day time drowsiness.

The worst of it is that I have seen absolutely NO benefits from the medication. I know it can take up to 8 weeks to see full results but seriously, absolutely nothing. In fact I am less productive and feel more scattered because of the constant exhaustion. I can't focus on anything at all.

I don't want to quit this quickly. I was warned it might take a while to find the right medication. but I don't know if I can continue with this. it makes me less functional than with full blown raging unmedicated ADHD and that's just not ok.
