Sometimes the rebound effect is worse than the initial symptoms you experienced or it can make other symptoms you have had so much worse than ever before. I truly believe it's the body trying to seduce you back into popping that little white magic fix. Cold turkey is not always the safest approach and definitely not the easiest so well done on your perseverance. I cold turkeyed it 2 years ago and had 2 grand-mal seizures, won't ever do that again...
