I started tonmya several weeks ago. Even though I couldnt really feel its affects at first..once is started taking 2 tabs at night I started sleeping better without pain awakenings all night long. I do not feel dizzy, drowsy day of or next day sleepiness. Im pleasantly pleased with how I have been affected so far. I cant wait to see if this gets better the longer I am on this drug. The taste is not pleasant , the numbing affect wears off fairly quickly. Please try this med. Its had an impact on my night pain and sleeping through the night. Which is like a taste of heaven for me. ALSO I HAVE A ZERO COPSY USING THE TONIX COUPON NOT BLINK RX. I have my husbands insurance for my meds. Give it time at first I didn't think it was working at all.
