I have a suggestion. With the money you're paying for the pills,you could see a doctor.
You don't need insurance for that.
Get a check up,talk about this issue and ask for advice.
For withdrawal symptoms,it's all about time. It gets better. Keep yourself hydrated,eat well,( not snack stuff/carbs ) get some Immodium and just keep moving forward. Exercise will help tremedously. Hot baths are your best friend.
Keep posting!
