I thought tea would be a healthy substitute and i know the PWA book recommends oolong and green tea but I have grown skeptical due to this recent experience i had with tea:

I saw a box of lipton tea in the grocery aisle and thought I'd really like to learn to make tea. So I purchase the tea, go home and follow the instructions on the back. I use raw cane sugar to sweeten it and pour it over some ice and successfully make some yummy iced tea.  I was so proud of myslef and thought it tasted so darn good that I indulged about six full glasses by myself.  About two hours later I went to bed and realized I wasn't falling asleep as easily as I usually do. Then, very suddenly I began to have A lot of thoughts. This progresses very quickly and I'm soon faced with racing thoughts   I burried my head under my pillow cuz I serioulsly believed in my mind that the world was coming to an end. I thought about calling a friend for help, but I couldn't focus enough to scroll through the contacts in my phone. I guess I eventually fell asleep, however when I awoke I felt very worn out
  That's when  it dawned on me that tea has CAFFEINE in it.  I never drink caffeine..and I had like, five or six glasses of tea that night.

A few days later I went to a friend's house and she offered me a glass of red diamond tea. It was all she had to drink and I was very parched and  I figured one glass wouldn't hurt(especially with ice, so it was more like half a glass)--but very soon my brain and mind started to race AGAIN. Not near as bad as before.. but enough to bother me. 

Why does this happen? Isn't the caffeine in tea sposed to be like, a natural thing???  Is cafeeine a drug or something?? Has anyone else had this reaction??? I can drink pop(though i usually never drink it) and the caffeine in pop does NOT have the same effect at ALL!!!  Pop just makes it take longer for me to fall asleep at night with it  in my system. Can anyone explain this???  I hated my experience with tea and when I see the box of tea in the cupboard I nearly get scared cuz it reminds me of what happened. I really hope someone can help me.

I really appreciate the both of you taking time out to read my long post. I will take your advice and steer clear of caffeine in the future. I also wanted to tell you that i googled my strange reaction and got this:

Yes, You Can Be Allergic To caffeine.

Some people have asked if people can be allergic to caffeine. I’m no doctor, but yes. Yes, you can be allergic to caffeine. And it’s not something a lot of doctors have known to look for. The effects of caffeine allergy look like some more severe mental disorders.

When you’re suffering from an allergic reaction to caffeine, one or more of the following things can happen: “loss of focus, intellectual deterioration, delusions, loss of judgement, and other symptoms of poisoning.” Because many people don’t properly recognize the caffeine allergy, they continue to ingest it (and why wouldn’t they?), and that can damage the brain and make things worse.

With symptoms like loss of focus and delusions and symptoms of poisoning, it’s no wonder the reaction often goes improperly diagnosed. What is diagnosed? “ADHD, anxiety, schizophrenia, bipolar disorder, OCD, TMJD, PMS, and other conditions.”

If your doctor diagnoses you with any of the above, and you ingest a lot of caffeine, make sure he rules that out as a cause before putting you on a lot of drugs.

So I'm thinking I'm either allergic or had poisoning from all those glasses of tea i consumed that night....
