Chantix and stuff works

I took the recommended dose for the first month. I felt really good (except the dreams) Then I suddenly got very depressed, lost feeling in my tongue,could not sleep. I felt horrible and would just go to bed but never really slept like I was in La La land. I cut the dosage in half which helped alittle and eventually cut it to 1/2 pill a day.The headache started then. I quit smoking for 2 months. I felt so depressed I started having 2 cigs a day. I felt less depressed as it was at least something I could look forward to. It has been a month since I stopped taking the Chantix but I still have the nasty taste in my mouth and numb tongue. The stuff works but I don't know that it is worth the side effects. Pizer blames all the side effects on withdraw from the nicotine but I have heard too many horror stories!
