Today is my third day sober technically, but my main addictions have been H and speed for as long as I can remember. Today is day 6 off of the two of those. I am still having stomach problems as well.
In April 2009 I was sober for a year. My days all tend to run together, but I think after about 3 months I went to a doctor and was given medication for my stomach issues.
The cravings never left me. I had good days, and even good weeks. Then when I would least expect it I would find myself desperate and willing to do anything for them.
Hope this helped. Stay strong. Let me know if you want to talk.
