Hey Snowtown, it is perfectly natural to worry about withdrawal symptoms on a certain level but, think about the effects of long term abuse instead! I had a few sleepless nights etc but my body was performing better in general within 2 weeks or so.
You will be fine, believe in your own mental strength and things will take a turn for the better soon.
Be safe, seek medical advice if you feel unwell and live strong, live true.. Be you.
