Expect to feel terrible and you will.

Inserts from medication packs are obliged to list every possible side effect. Whether they were documented and directly attributed to the medicine in question, or self reported by a worried parent/carer with no definitive connection whatsoever.

In more than two decades of using Methotrexate, a medicine often feared for the potential side effects, I personally experienced no side effects whatsoever. However, during this time, I honestly wasn't aware of the existence of most of them.

I was lucky, but not alone.

It's similar to how expectant first time mums, hear everyone's horror stories.
