yeah, that was the issue when 10 years ago i was on valium. When i look back, i had only taken xanax for probably 2-3 months max...granted i was all over the board towards the end taking sometimes up to 3mG a day the Dr back then started me on 30MG of valium. Looking back that was way too much, i was dizzy all day and doing crazy things cause i was so high on it. And because of that it took me over a year to get off it because i had to step down off of 30mg. She should have given me more like 10-15MG. This last Dr. when i went in for valium tried to start me on 5MG valium even though id taken .5 for a few months so....yeah when i told her the crossover is 10MG she didnt like that. I think to become an EXPERT, they need to get an addiction going themselves and try to get off of it using all methods. lol. I mean the conversion tables are not that hard to find, do a google search for christs sakes its all over. How they come up with these numbers i have no idea.
