Side effects differ in different people, so there's no way to know. The more stimulating antidepressants generally have fewer weight issues, but can make anxiety worse. Sometimes mixing an ssri with a stimulating drug can help with this, but then you're taking two drugs. Remeron has the reputation of the worst, but again, it depends on the person.
Your pharmacist and or doctor can advise. You need to see the doc to get a prescription anyway.
