I may not be the best person to give advice here given that I have failed to quit meth every week for the last few months. However it is still on my to-do list and I’ve managed a few weeks of abstinence here and there.
As far as how you will feel, usually the first 2-3 days after your last use feel fine but around day 3 or 4 you will become incredibly lethargic. Like totally unable to get out of bed lethargic. However how bad it is depends a bit on how heavy and how long your use was. If you are unlucky, this is when your major comedown will commence. It is common for the first experience of a meth comedown to be pretty horrific, with lots of anxiety and existential dread verging on panic with a side serving of bleak despair. This does not last too long, maybe 2-3 days, again depending on prior use, and it can be alleviated with benzos (alcohol tends to make it worse). Some people find that an atypical antipsychotic like Seroquel or Abilify will completely block the comedown horror. Once that passes you will begin to move back towards your baseline normal mood over a week or two, although you may find yourself more anxious or depressed than usual for sometime. During this period you may find that you are aggressive and quick to anger. In a month tops, you’ll feel fine.
Your enemy is cravings. They can occur anytime from day 2-3 up to weeks or months after your last use. They are extremely difficult to kill and you need to develop some kind of strategy to cope with them [this is where my advice becomes theoretical as I’ve not really done this yet. But having a solid structure to your day with a number of small commitments to keep you focussed is recommended as is an exercise plan. Exercise is probably crucial - going to gym same time everyday is a good thing. Another crucial thing is to have someone who knows what you are going through that you can vent to and talk with when cravings get bad - talk it out with them until the feelings pass. Doesn’t have to be a fellow drug user, I once used my dad. In fact, it is best to get all drug users out of your life and delete their numbers and possibly change your phone number. Needless to say that goes for dealers as well.
Finally, hydration and good nourishment speed the recovery process.
There is actually quite a lot of other useful advice but digest this first and we’ll see what anybody else has to add. It does not sound that you have been using for that long, so your comedown and recovery might be relatively easy.
