I would stop using psychedelics they are not healthy for the brain. Also avoid ADD medications at all costs.

Try L-Theanine and Caffeine combination in a 2:1 ratio. L-Theanine is very safe, it is a calming drug that also enhances focus. When used with caffeine it reduces the negative effects of jitters/anxiety while increasing focus. It is the calming agent in tea.

I was on medication for a long time and it was a nightmare.

There is only one solution:

The combo I outlined above (which is actually amazing), good diet, good exercise, and good sleep.
