First, you are going to be ok. That is important for you to hear.
I am experiencing a long-term recovery, and I have had contact with others that are worse off than me, so please believe me that you will be ok.
If I am willing to say it, then it must be true.
5-htp may help, but it may also make your anxiety worse. Use your judgment and discontinue use if you don't like it. Piracetam, choline, and fish oil seem to be the most effective combination for those having real problems from E use. I highly recommend them.
Exercise is a great idea - I recommend it to ALL in recovery, but not necessarily in the first week. Honestly, it would have killed me in the first two weeks, but that's me. After four weeks of hell, I discovered Piracetam and began eating solid food again....workouts soon followed and have made all the difference in the world.
You need to know that you are at an increased risk for stroke. Serotonin plays a major role in blood distribution in the brain, and you have drastically decreased the amount of serotonin in your brain. It can take 3 months for the body to start synthesizing more of it. In the meantime, your brain is going to pull out all stops to restore blood flow. Depending on the amount of damage done, this change can result in visual/spatial distortions.
So, have you had any changes in vision or feelings of dizziness?
Does the back of your head buzz?
How are you eating?
If you don't have any major complaints in these areas, you should be fine within a week or two. A month, tops.
Let us know how you are doing.
Don't forget the piracetam, choline, and fish oil. Also, get some tumeric extract - its a great anti-inflammatory. Aspirin is ok too, but leave ibuprofen and Tylenol alone.
If you can exercise, go for it.
