What Activities Should I Do to Avoid Fast Wear off of Botox Effect?

Botox is quite expensive and it really hurts my budget. But this is one beauty enhancement that i think i wouldn't like to give up. Kindly give me tips on how to prolong or extend the effects of botox for more than 4-6months. What activities or factors should i avoid so my Botox does not wear off easily? Thanks - Hearty
