This. If there is one thing I've learned it is certainly not that you can generalize from yourself to others, especially for medication and its side-effects and withdrawal effects. I get so sick from taking novalgin that its a medical emergency (Agranulocytosis). Apparently, this occurs in like 1 case in a million. Conversely, I've heard of horrible side-effects or withdrawals from other medications where I experienced absolutely none of them.
