You need to wean yourself from the laxatives, as you can seriously harm your colon over time. Your doctor can order Miralax for you, temporarily, but ultimately, you need to get off of the laxatives.
In addition to weaning yourself off of laxatives, you might also consider seeing a therapist regarding your self-medication to lose weight.
