There’s no way in my opinion it’s going to be straight up horrible. Based on what you shared don’t go into this with that mindset. It’s going to be what it’s going to be. I was non stop addicted to opiates (iv heroin, fentanyl, methadone, any opiate under the sun) for 15 years. At that rate yes of course my withdrawals weren’t going to be fun but my mindset was what I mentioned above - it’s going to be what it’s going to be. Please don’t plant seeds mentally about it being horrible. So much of this is mental. Your going to be fine
