How do I ween myself off texting?

I switched cellphone providers and they gave me 3 months of free everything, basically. The end of this period is in June. I’ve been texting a lot since I signed the contract, and it’s all been free. In June, I’ll only have 75 texts, and my bill i already very high and I cant afford to go over.

Are there any tricks I can learn to become less dependent? I used to never text before I got my iPhone.
