? regression with DMSA - need advice

[Guest guest]

We just completed our 2nd round of DMSA. Our first round consisted of

little improvmenet but slightly imporved sentence structure and the

following 11 days he did well. The second round he was very

irritable. He has regressed some from there. We have never seen

regression with him only steady improvement. His sentence structure is

worse, he is word-switching, not as social, not asking as many

questions, less focused, etc. Any advice? Is this to be expected?

Any input is appreciated.

One more question: what is the recommended dosage for taurine? Out-of-

town with my CSB book.

Thanks.
