Yes, but not that much (about 2 kilo in 2 months).

(1) 体重掉了40磅 and 腹部疼痛

Could it be Metforformin's side effects?

(2) 脱发

There are many on-line forum talking about Simvastatin's side effects

I have noticed that some people do complain about hair loss

(3) 便想用一组中药来代替

My GP has advised me:
either take a lower dose (20mg)
or switch to a better statin
or try with diet & exercise for time being.

Also, I have been told that Q10 supplement
can help to reduce muscle problem.
