OMG. I have just tapered off topamax/topiramate after six months of taking it. It is horrible. To note: it is awful combined with alcohol, absolutely exhausting. The combination is not something that I would describe as a 'buzz'. About 20 to 30 minutes after taking it I would become extremely hot... we are talking no blankets in the middle of winter. For example, if I had been reading in bed and then took topamax, 20 minutes later my blankets and clothes would come off in a cold bedroom. Strangely enough, throughout the day it would become difficult to get warm again if I felt cold. It absolutely messes with your thermostat.
It is very much like Epilum in that it is used as a mood stabiliser and/or to prevent seizures. You have to taper on to it when starting out because of the risk of heat rash!
It is also used as a treatment for bullemia. I had it as a mood stabiliser after bad flashbacks from PTSD. It is a real appetite killer. It stops bullemia because you just feel 'sated'.
It makes you emotionally numb. Perhaps it was her mother's? Not a fun drug. At all.

ETA: I even complained to my psychiatrist about feeling nothing when my friend's dog died, ironically. I was willing to have PTSD flashbacks rather than continue with that drug!
