I think the max safe dose depends which study you base things on, and varies depending on the doctor and country, but yes I was well into the 300s per day at the peak. It didn't feel necessary and I couldn't justify the side effects for long.
The withdrawal today has been fairly noticeable. Not in a "I wish I could take some venlafaxine right now" kind of way. More like a dizzy (sort of) feeling, combined with slowed thoughts, a sense that my brain has run out of lubricant or fuel, if that makes sense. Even my hearing and vision is reduced at the moment. Everything's just sort of.... less. But I've felt this before (I lost my pills when I was homeless) and I know it's temporary. I think my brain is slowly adjusting to the lack of ... whatever the pills provided. Pathways are adjusting, levels are normalizing, dormant areas are powering back up. I think I'm going to be one of the lucky ones.
Thank you for asking :)
