It was the best thing I ever did. I did gain about 60 pounds but I was diagnosed with a thyroid and pituitary problem all at the same time.
I couldn't use Zyban but I used the patch and it really worked for me. The first week I put it one my chest for more absorption and I also put it on just before I went to bed so I wouldn't be having nic fits when I woke up in the morning.
I have saved so much money it is unreal. In the first year I saved enough money to buy a sofa, loveseat, wing chair. ottoman, cherrywood coffee tables and sides, lamps, paint, curtains and rods for my living room. I saved over 4 grand. Amazing isn't it!?
Keep on trying, its worth it.
