How long after upping dose should depressive symptoms subside? 150>300

I was on 150xl up until January for a year, and stopped. I started 150 again in April and it just wasn’t doing much for me by mid June and I was really irritable, had brain fog, word recall issues, memory problems.

Today is day 10 on 300, and I’m really questioning whether all of this is worth it. It’s the middle of summer and I just feel like I want to be inside all the time and by myself. I feel lifeless, like there’s no point to doing anything and also just angry having to go through all of this. I seemed to have *some* peaks of more energy for a 2-4 days somewhere in the mix but the rest has been depressing.

Honestly, I stopped in January and felt fine for the most part, I only started again because of specific stressful event I knew was coming and now passed and I feel like I’m making a mistake. The only thing stopping me is the potential for this to help ADHD symptoms I know are there.

Any words of wisdom/experience? :(
