If I'm going heavy there's a good 5 days give or take a bit of feeling like a thousand pounds, no energy, diahrea, weird chemical caustic feel, it's rough. Meth is the most psychologically addictive of the big.druga too so relentless desire to re-up.
I have Been using amphetamines over 20years More or less, meth about 8 years, not all The Time of course. I prefer meth over amphetamine, psychosis and physical discomfort with amp IS always toi much for me, i hate being so bored and psychotic at The same Time. But with meth, no psychosis or boredom at all, until being awake for too long. Meth satisfies for a long Time, good shot makes you feel good for a long time. 
How many days a week do you use meth over these 8 years? And at what doses? I think frequently and dosage matters. I took ~25mg daily for about 4 weeks for ADHD until I was prescribed a stimulant medication. But I took a week break before starting the stimulant medicine. Personally I felt symptoms like mental fatigue, lack of motivation and general depression for about 5-6 days. At most a week.Yes, i can't wait to use it next Time
I hate those withdrawals though, i get them every time i use meth, it is weird how strong they are, or is it me who feels them too strong, am i overly sensitive i dunno .. They are pretty much physically unpleasant and i would take meth withdrawals over benzo withdrawals for hundred Times..
I usually take 150-300mg a Day, 2-5days binge. And once of twice a month maximum.
I’ve tried to stop use often at various stages of meth addiction. Diarrhea but very temporary, irritability, emotional and then sleep and eat and sleep. Once rested intense craving follows. I do know after dependency the crash is far less intense however the rage factor increases and lethargy goes on forever.
