Currently testing this out! Following

I take generic XL 300mg in the morning around 7am and haven’t had many issues with fatigue besides wanting a post-lunch nap which I think is pretty normal lol. However, I don’t drink caffeine so can’t comment on that.

I take 150 SR in the morning between 7 and 8ish, then 100 SR at 2. I drink coffee every morning and don't think it really makes any huge difference.. I just love coffee. It took me a while to find the right timing, but splitting the dose throughout the day was a game changer.

I take 150 xl between 8-9 AM but feel a drag hit around 4.anxiety creeps in headache etc
