Helium symptoms and conditions

I have been on this about two or three months. In the last two months I developed hoarseness, laryngitis, and loss of voice. I sound like Mickey Mouse or like I have been sucking helium.

Any one else have these symptoms?

I also have powerful leg and foot cramps at night but may have had this before.

HELP

I have stopped for about 2 weeks now and no improvement. Anyone have an idea how long this could last? I need my voice for work.

HELP

i have been taking this med for 3 days and i feel like my head is full of helium and very dizzy plus i seem to fade off into my own little world doesnt matter where i'm at driving sitting and thats not safe.
