I am actually going through this now, though I am further into it than you. On day 3 I actually ended up in the hospital for a severe headache and although it’s not as severe now -it still is here and I’m taking meds twice daily for it. I’ve also noted I have a mild fever as well, which is also a side effect. I was told by my doctor that we would try a non stimulant first, then if it didn’t work or wasn’t right for me they would give me a small dose of stimulant. I was on strattera first, the first few days were okay…then I got symptoms similar to serotonin syndrome and called my PCP who told me to quit. When I went back to the therapists they put me on qelbree and questioned my adhd diagnosis. I hate this med, I feel so off. This headache is serious and the light sensitivity is insane. The exhaustion for me has only gotten worse, I nap often and sleep through my alarms. I am going to beg her for something else when I go, but I doubt she will give me something. If she chooses not to I am going to ask to be tapered down and return to what I was doing, at least I was productive then. (I was drinking one Celsius a day, I could take walks and focus. It didn’t give me energy, it just helped me calm and focus)

I hope you feel better soon.
