Anyone had a bad reaction to Suntheanine?

I have started taking Suntheanine 150mg to combat anxiety. I have taken it three times now on different days. I feel like I am reacting badly to it. On the first day I didn't really have any reaction. The second day I took it sublingually I could not sleep and had palpitations and racing thoughts. I did drink this with vitamin c so not sure if that would have caused a bad reaction. I took it today again and got extreme nausea/loss of appetite and a raging headache and just a little sleepyness. I don't understand why it is not agreeing with me and this is so frustrating. Has anyone else had this kind of reaction. It is the Doctor's Best brand of Suntheanine.

I have read a couple reports of people having sleep issues with L-theanine. L-theanine does increase dopamine in the striatum, and serotonin in the hippocampus and hypothalamus. So perhaps you are just sensitive to these changes.
