I never experienced what you had but I had about 2-4 days of pure hell. What I experienced:
- not being able to hold anything down even water
-I would go from hot to cold and back to hot immediately
-I would almost pass out even going to the bathroom or the kitchen for something to drink.
-ate some stages I was hungry, but even the sight of food disgusted me and I literally couldn't eat. Even if I managed two bits or swallows, my body couldn't process it.
-the worst heart burn I have ever experienced, I would eat tums like candy,
-I was extremely restless. My brain and body was racing. My heart felt like it was going to explode. I couldn't sleep even though I wanted to. I did have audio hallucinations.
I have been asked to describe the detox process from a few people who were curious and I described it as 4 days of pure hell that no one should go through.
