Ok to make a long story short I got a little chest/sinus cold and decided to take some Mucinex MD. Now I've taken the generic stuff before. I usually do 400 mg of guaifenesin. Well two pills of Mucinex is like 1200mg.

I pissed about a lb of water off about 2 hours later. i couldn't sleep. My throat felt like 2 miles of dirt road. I woke up and pissed out a kidney, and probably pissed another lb out the rest of the day. This was on Tuesday night. My workout on Wednesday felt weak and basically dehydrated I could tell. Friday morning I feel like my hydration is just now getting back to normal.
I couldn't drink enough water without drowning myself.


Just thought I'd give you the heads up if you ever want to take this stuff. I think 600mg is the max i'll ever do again.
