When I was younger drs tried putting me on several different antidepressants too just like they did you. I took
wellbutrin,
zoloft,
celexa,
lexapro ... the list goes on. I don't know why I continued to take all of these meds. They did absolutely nothing for me whatsoever except make me gain weight.
The bottom line about ADs is that they don't work the same for all of us. In fact they don't work at all for people like me and it sounds like maybe the same for you.
If we don't have a true chemical imbalance they don't do anything positive for us at all. Drs RX ADs all the time. I think they are the most over RXd med on the market. For people like me who take them it's just a waste of time and money. I am not nor was I ever clinically depressed. I was just PI$$ed off. There is a lot of difference in being clinically depressed and mad.
Lots of people get RXd meds who shouldn't be receiving them. Drs play a guessing game with meds based on our symptoms. They make educated guesses, but guesses none the less. Same for ADs as for pain pills, benzos, and what not. But this is another reason why I always say to keep the dr in on what is happening so if these drugs don't work properly we have accurate records to fall back on. Drs need to know exactly what has taken place or they can not be expected to diagnose and treat anything properly. That is just common sense.
For what it's worth, I see nothing wrong with stopping cigarrettes the same time you quit taking drugs. I stopped cigs the same time I stopped drinking and taking street drugs. Plus I started a major diet at the same time. I always figured that if I was going to be miserable anyways, I should just go ahead and get it all over with at once if possible.

Of course that is just me. Lots of people would say I was nuts for doing that. But I am still cigarette free and clean from drugs. God bless.
