It takes time for things to straighten out. When I was drinking,(I rarely drank alcohol till 5 or after). But at lunch I would need 2 or 3 refills to get "rehydrated".
That didn't go away till probably a year after I quit drinking. I have kingsize water glasses at home. I always wondered why people bothered with tiny glasses. Now there is no way I could drink 2 of those glassfulls of water like I used to. I drank for 30+ years so I didn't expect things to just turn around all at once.
One thing about it. When you first quit drinking 3 months ahead just seems like a lifetime. But if we stay sober and just don't pick up that first drink. Before you know it your looking back, and a year seems like a few days ago.
Time does fly.
