Help please.

I hit tolerance at .5mg of Ativan after about a month and a half of use, which was about a month ago. I accidentally dropped to .35mg in about a month and was suffering horrible from wd and very bad adverse reactions. I tried to cold turkey as of yesterday and have gone insane in less than 48 hours. I reinstated V today at 1.5mg just to see how I do. I know 3.5mg is the equivalent but I just wanted to see how I do on a lower dose. Thoughts on this? Ativan was giving me serious adverse reactions making me delusional.
