Methadone Withdrawal?

I had taken Methadone at 170mg for 3 1/2 years and the last 9 months tapered at 5mg a week to 10mg the beginning of may. I got down to 5mg and on the 5th jumped off with the thought of just taking some Lyrica, Neurontin or even weed. Well it's not been too difficult I relapsed a couple of times with some clonazepam, oxy's, ambien and I think, oh yeah some flurazepam. Other than those three days nothing but lyricas, neurontin and weed. I know that the other things are cns depressants but I also know the difference between those and withdrawal feelings. I can barely get out of bed at 42 years old and the only thing I can do is to walk my dog everyday and eat some breakfast/lunch & vitamins afterwards then water the rest of the day or maybe even ice cream with peanut er. You know anything that tastes so good you can eat it even when sick like cheddar cheese perogies. Back to the question it's been 18 days and only cannot sleep well and like 40% energy at max and it just sucks arseto the max. I feel like I'm dying but it's so slow and just stupyfyingly [sp] mind numbing. I am not looking for a best answer as much as just maybe how much longer this should be I hear usually 21 days but that might be pushing it and life doesn't stand still for me unfortunately. Is there anything I should do other than what I have been and I wish Ibogaine was legal in the USA so once again a great drug that could help end addiction so much better than the drug companys that run this country with the banks it's all related so fuggettaboutit. Please if your thinking of taking methadone for heroin or painpills don't the withdrawal for those are like 4 days compared to this crap and suboxone is even more evil. Ugh thats it peace out.
