Side effects - Getting Sick every comedown.

[BigP]

My Friend Swim is having a huge issue lately, that every time he decides he wants to party, he has an incredible night, he doesn't overdo it, hes very in control and he has a great group of friends that he spends the next 12 hours with in an apartment just hanging out and relaxing, smoke a few bowls, just fall asleep nicely, and sleep everything off.

Everything is great, and he had been doing this for about 8 months at this point. However he recently told me (about 3 months ago) that every time he decided to party, the next week, although feeling NO negative effects, aka hes very happy and relaxed, hes seeing his GF with no relationship issues, everything is perfect. He tends to get this terrible cold. This is swim explained it to me.
He says this is what he feels.

Note: He doesn't get every symptom every time.

- Slight - Strong Fever.
- Runny nose.
- Cough
- Sensitive skin
- Sore back

It seems as if every time he goes out, he picks up a mild flu, and it is really starting to annoy him (as you can imagine) For the next 2-5 days he is totally out of commission, and whether for good or for bad, it is causing him to party with his friends less often.

Now some back round information. Swim also happens to live somewhere that had a very cold winter, and normally leaves the party to -10 or colder temperatures. However, normally cold is a complete non-factor, and doesn't cause swim any discomfort.

His question is this. What can possibly be done to prevent his colds. I really feel bad for him, not because it affects his every day life. But who wants to be sick that often.

Also, swim normally has an INCREDIBLE immune system, and used to get sick once a year.

Ps, Swim would like you to know, he only parties maybe once every 3 weeks. And doesnt drink / smoke, and only smokes weed when he is rolling, is in good shape, runs goes to the gym, and is in over all good health.
