I have been having a problem with bloating in the upper stomach area for the last couple of days. I used to drink alot of diet drinks (about 3-4 a day) and also use Splender. I have stopped since around 3 days. I also have problems with gas, constipation and diareah. Today I feel sluggish and very bloated. I am currently taking trazadone and xanax for aniexty. Please any advice or thoughts on this matter.
