Hi, I looked at your profile it so I know a little more about you. It says day 3 off trams and hydros. I understand how your feeling right now. The "antsy" feeling is hard to deal with. You probably feel really irritated. Look, your on day three so your almost over the hump. I always felt the first 5 days were the worst. Try to do some light physical activity...maybe a walk a few times a day. I drank a tea called Kava, it helps with anxiety. The most important thing is to stay the course...look at the 3 days you have done and realize you don't want to have to have to redo those someday. Keep moving forward.
Hang in there and God bless
Using is NOT an option. Get yourself busy. Go for a walk, turn on the music, just do something.
DITTO From above. Its the itty sh**ty part of the brain that rewinds the tape back. If only......Just hang in be strong and do not give into the beast. Give yourself a pat on the back for the time you have and that there will be Blessing in the long run.
