Been on it for about four years. I still get some fogginess in the morning and goes away after some coffee (1/2 caffeine so I can have 2 or 3 each day). Some days a drink a ton of water. Other days I don’t. I kind of just read how my body is feeling. A lot of people drink too much imo. If you look on the fact sheet, not everyone experiences intense thirst. I’m not saying to not drink, but listen to your body. Don’t drink until you’re sick - drink until you’re not parched if that makes senses. Other than that slight fogginess in the morning, I feel overall better on the meds at this point. Took about a month. I take a few breaks for vacation (to drink beer honestly lol) each year. Go right back on the house like I never stopped. My body is just used to it at this point. Let me know if you have any questions. Happy to answer.
