Unfortunately it's one of those situations where you'll never know unless you try
I wouldn't pay much attention to those saying not to take them, they're only speaking from their own experience and yours may be totally different. I was on AD's for three years and although the side effects were horrible at the beginning, they really helped me long-term. But I'm aware others had had terrible experiences on the same medication that I took - it all depends so much on the individual and how they react, not every drugs works well for every person.
You seem pretty clued up on the potential negatives of taking side effects so it would be a good idea to discuss these with your GP. It may be beneficial for you to start on a small dose with constant monitoring from your doctor and see how you go from there.
