I started taking the 8mcg x 2 about 2 weeks ago. This did nothing for me except help with bloating so I called my doctor. The doctor has prescribed me 24 mcg x 2. I have been doing this for about 4 days now and I have see no improvement. How long do you recommend that I "try" the amitiza before giving up? Also, what is the best time and intake to go along with this medication?
