My diopetry has been changing very radically the last week, +/- 1 unit within a day (my rx is ~ -2). The only thing I can think of that might be causing this is temezapam withdrawal: I stopped the stuff altogether a week ago (30 mg), replacing it with clonazepam (1.75 --> 2.25 mg). Does anyone have any input on this? It seems like such a strange withdrawal symptom. One minute I'm looking at the world 20/20 through my glasses, an hour later I might as well not be wearing them at all.
