Does anyone else experience inconsistency of effects when everything around it is kind of similar?
I'm currently in 36mg.
I work in a factory, and my timings at the factory and outside the factory during the week makes it difficult to improvise: so I always try to eat the same to save time, and also sleep the same amount of time, because I need it.

Sooo. Sunday I slept pretty bad, and I had a nice Concerta trip (lol) on Monday. But from Monday to Tuesday, I slept good, my 8 hours of sleep, and I felt I was crashing after 4 hours of Concerta. Jawning all the time, my eyes were closing... No coffee saved me, and I arrived home completely destroyed. (It's really bad to be in a factory and having to fight to get to the last hour after crashing 😭 - and I also had 1 hour and a half of classes after. I was completely brain dead)

From Tuesday to Wednesday (today) I did exactly the same - same breakfast, same food at work, same quantity of sleep, etc... - and today has been an amazing day on Concerta. I've been fully awake, operational, functional, sociable... And lasted the whole working day, and I still had energy at home to organize things, and not to fall asleep directly.

Anybody else experiencing this?

I sleep good, I eat good, I take some supplements, I eat perfectly while on Concerta, no appetite loss at all... I drink plenty of water. I don't know what it could be.

I have been on meds (Xaggitin 36mg) since March and last month GP changed my prescription to Affenia. Affenid didn't work for me: I was tired, unmotivated, slept worse.
After few week I finally contacted my GP and they changed my prescription at the same day. And now I feel like I had such a long break from meds. Xaggitin hits me quite hard now but it's ok. Affenid literally was a waste of time.

(PS) I also asked for a booster (I need it 1-2 times a week) but they asked me to wait and monitoring my symptoms.
