Brain stimulation

It makes me wonder if they really want to find a to find things that help with Parkinson’s, take for instance when I take a pregabalin before I go to sleep, the next day it a great day I can workout do what I want to do till about 8 in the evening. But only take them for 2 days then have 2 bad day as the don’t work the same other wise, but what I’m getting at is why isn’t someone looking into what it is that’s stimulating my brain, your not theme I’m the only one to notice this and they must be similar drugs that do that same, and don’t give me that there addictive, I’m already on addictive Parkinson’s drugs, anybody that’s tried to stop there Parkinson’s drug will tell you how bad it feels trying to stop them,
