All medications have side effects. All of them. Some of us are lucky and don't get them, but there aren't any meds that don't have side effects. Our bodies evolved to eat, not to take meds. This problem is multiplied when you start on more than one drug at a time. I see why you did that, as you were apparently treating withdrawal problems, but start up side effects are pretty common. Some of these go away as your body gets used to the drug and some don't, and it's a very individual thing. But it isn't anything particularly attached to just these two drugs, it's all of them. Even aspirin eats the lining of the stomach. So these might go away with time and they might not. Only time will say. But you don't say what your withdrawal symptoms were, so it's hard to know if some of this is because of withdrawal or going back on the meds. Getting a panic attack could just be because you no longer were taking the meds that were preventing that, if panic attacks was one of the reasons you went on them in the first place. My point being, it doesn't matter if anyone else had this problem with these drugs or not, as we tend to react differently to medication, and you also don't say if you went through any of this when you went on them in the first place. What matters is what you're feeling. When I took Zoloft, I got no effects at all and no side effects. It's just a very individual thing.
