I was on aprox 250mg a day for about 15 years. I was very deep into addiction. My recovery has been tough, but doable. Exercise, rest, food, and sleep have been very healing. I also take Wellbutrin, which had really helped. The constant fatigue and brain fog have definitely gotten better at this point, as well as the constant appetite. I'm taking one day at a time, but I'm doing great. The first month wasn't fun at all for me.
