diamox and Topiromate

I was Diagnosed with IIH back in July, I started out on Diamox at 250mg qid and was unable to handle the side effects so down to tid we went, seemed to tolerate well but the swelling in my right optic nerve increased so back up to qid we went.  Now the side effects are unbarable.  So back to the Neurologist we went, he prescribed Topiromate 25mg QD increase by 25mg once weekly until on 100mg at bedtime.  Becasue of the interactions between the two I need to come off of the Diamox to be on teh Topomax (topamax).  My question is has anyone else done this successfully?  come off of the Diamox and still had good luck with the amount of pressure\swelling on the optic nerve with the Topomax (topamax) or am I just  setting myself up?  Any insight anyone could provide, or experiences would be great.

Thanks
Tracy
