Very effective.
Wife and I used it starting about 3 yrs. ago.
Last puff, Labor Day 2012.
Took 1 tab in the AM and 1/2 tab in the evening. Avoided the insomnia that way.
No other side effects.
I’m a strong proponent if you can take it. I could.
Tried Wellbutrin some yrs. ago That stuff made me very short tempered.
Stopped after 1 week.
My doc had me try Wellbutrin. Lasted about 2 wks til the family pleaded with me to start smoking again. Apparently I had turned into a huge witch! lol It was the insomnia. I could sleep for no more than about 10 minutes at a time.
Almost a year and a half ago I used ecigs to quit. Easy.
