关于一个so much的问题

Xiaotongdi

Most insomnia is not an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications, anxiety about travel, or stress before a job interview.

1. an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications
   
2. an illness or a physical condition so much as symptomatic of another problem that may be a simple one, like a reaction caused by certain medications
   
3. so much an illness or a physical condition but a symptom of another problem that may be as simple as when certain medications cause a reaction
   
4. so much an illness or a physical condition, but it is a symptom of another problem, maybe a simple one like certain medications causing a reaction
   
5. so much an illness or a physical condition but symptomatic of another problem, maybe simply a reaction to certain medications
   这个so much是怎马一回事？为什么要用呢？
